Cassette Sizes and Types

37 mm Filter Cassette

Clear Cassette Housings 25mm and 37mm for Personal Air Sampling ApplicationsAvailable in both a standard two-piece style and a three-piece style. These cassettes meet the NIOSH requirements for sampling most dusts, fumes and mists. Three-piece cassettes allow open face sampling, typically for asbestos and other fibers.

25 mm Filter Cassette

Available only in three-piece style, this cassette is used only for "Open Face" sampling and meets specifications for asbestos sampling, as described by NIOSH, OSHA and EPA. It has a two-inch extension cowl, assuring proper fiber distribution for microscopic fiber counts. The carbon imbedded body reduces static charge. 

Membrane Types 

PVC, Teflon, Glass fiber, Silver, Quartz and MCE (Mixed cellulose ester).

Cellulose Shrink Seals

Available in both 25mm and 37mm sizes, these bands are applied wet around the cassette and shrink when dry to form a tight seal. The seal provides a positive non-tampering indication when the cassette is received by the lab for analysis.

Cassette Holder

Consists of tubing with clip, designed to mount the cassette to the worker?__s collar close to the breathing zone.

Filter Cassettes

Back Pressure for Typical FiltersWhile selection of a specific cassette size/type and filter membrane should be determined by  review of the NIOSH sampling guide, the following rules generally apply:All dusts, fumes and powders sampling – use 37mm filter and cassette.All asbestos and fibers sampling – use 25mm filter and cassette.Dust sampling – use 0.5 micron (pore size) PVC filter membrane.Most heavy metal (such as lead fume) sampling – use 0.8 micron MCE (mixed ester of cellulose) filter membrane.*
*Note: Metals form airborne vapors when heated, as these vapors cool and condense they become small airborne particulates, known as fumes.

Cyclone Sampler for Respirable Dust and Silica

Dorr Oliver CycloneThis Dorr-Oliver unit meets NIOSH sampling requirements for 10mm nylon cyclones, as specified for nuisance dust (#0600) and silica dust (#7500, 7501, 7601 and 7602).

It is designed to separate the respirable fraction of airborne dust from the nonrespirable fraction; i.e. airborne particles with aerodynamic diameters between 0.2 and 10 microns, capable of producing pneumonconiosus lung disease with long-term exposure. Designed for pneumonconiosus-producing dusts, it can also be effectively used to monitor the respirable fraction of all types of dusts, from high toxic to nuisance particulate.

The unit consists of a two-stage cyclone and a lightweight aluminum frame, which mounts a standard 3-part 37mm filter cassette, with membrane filter. When air enters the cyclone stage at 1.7 LPM (as recommended by NIOSH), the larger nonrespirable particles are centrifugally separated out and drop into a removable lower grit pot. The smaller, respirable particles pass on to the cassette, where they are captured by the filter membrane.

Cyclone GraphNote how closely the separation achieved by the Cyclone Sampler (red curve) follows the convention for separation of respirable particles, as specified by ACGIH (black curve). Few other cyclone separators show such a close fit of actual to ideal performance. For example, 100% of 10 micron particles and 50% of 4 micron particles are removed by the cyclone. This corresponds with 0% of 10 micron particles and 50% of 4 micron particles that penetrate the lower lung.

Cyclone Calibration Jar

Cyclone Calibration JarWhen ordering a cyclone sampler, be sure to also order a Cyclone Calibration Jar. Since a cyclone has only a single hose connection, this jar allows proper placement of the cyclone filter between the sampling pump and the calibrator device, as shown.

Inhalable Dust Sampler

Inhalable Dust Sampler

Meets ACGIH and MDHS 14/3 requirements for inhalable particulate
50% cut point at 100 microns when used at 2 LPM
Small (128 x 33 x 25 mm) including lapel clip
Light weight (< 1 ounce or about 25 grams)

When operated at 2 LPM the Inhalable Dust sampling head collects a dust sample that follows the particle size distribution as described by the ACGIH for inhalable particulate. The ACGIH descriptions applied to particle size selective TLVs are presented below.

Respirable Particulate Matter: Those materials that are hazardous when deposited in the gas exchange region (50% cut point at 4 microns). 

Thoracic Particulate Matter: Those materials that are hazardous when deposited anywhere within the lung airways and in the gas exchange region (50% cut point at 10 microns).

Inhalable Particulate Matter: Those materials that are hazardous when deposited anywhere in the respiratory tract (50% cut point at 100 microns).

Inhalable Dust Sampler Exploded ViewThe inhalable fraction size distribution is described by the following table. For particles of 1 micron diameter, nearly all (97%) are captured by the sampler and collected onto the filter. For particles of 100 microns in diameter, 50% are collected onto the filter. This approximates the size distribution in the respiratory tract.

Enabling Simultaneous High and Low Flow Personal Sampling Methods

Dual Port High/Low Flow Manifold for Air Sampling with the GilAir Plus Personal Air Sampling Pump

Simultaneous samples usings the GilAir Plus

Reduces air sampling time and costs 

Increases worker comfort


Monitoring worker exposures to airborne particulates, gases, and vapors often requires Industrial Hygiene and Occupational Health & Safety professionals to take multiple air samples from the environment of one worker. Such sampling may require a worker wearing multiple air sampling pumps or returning to sample on a different day. Setting up and deploying multiple air sampling pumps or returning to sample on a different day can be expensive, inconvenient, and uncomfortable.

 

Dual Port High/Low Flow Manifold for Air Sampling with the GilAir Plus Personal Air Sampling Pump

The Gilian Dual Port High/Low Flow Manifold enables connection of two different sampling media thus eliminating the need for multiple sampling pumps. Two manifold adjustments enable the setting of separate flow rates for each media connection. A single tube connects the Gilian Dual Port High/Low Flow Manifold to the GilAir Plus providing an efficient method for obtaining two samples from a worker during a single shift. 


The Dual Port High/Low Flow Manifold capitalizes on the unique high-flow constant pressure capabilities of GilAir Plus. High-flow constant pressure, one of four sampling modes available on GilAir Plus, maintains a constant negative pressure in the sampling train between the pump and manifold. In constant pressure sampling, adjusting the flow rate of either media connection will not affect the other. Similarly, sample media loading on one side does not affect the second side. 

The Dual Port High/Low Flow Manifold is designed for use in applications for sampling of heavy metals or asbestos fibers using two filter cassettes at the same flow rate or simultaneous sampling using a filter cassette and sorbent tube. In addition, sampling methods that do not create significant backpressure changes from start to finish may be accomplished using this manifold accessory.

Refer to the Dual Port High/Low Flow Manifold and GilAir Plus user manuals and the technical paper, GilAir Plus QuadModeSM Split Sampling in the High-Flow Mode for additional information.

 

Sorbent Tubes and Tube HoldersSorbent Tubes for single or multiple sampling of vapors and gases using a low flow sampling pump.

These high quality sealed glass tubes are 6x70mm in size, packed with accurately weighed, high purity coconut shell charcoal. The specific applicable test methods should be determined from the NIOSH Air Sampling Guide.

They are designed to absorb vapors and gases passed over them, when used with low flow air sampling systems and fit a variety of holders described here. A tube has sorbent material in two sections: the first for sample collection and the second for sample break-through control.

The tips of the tubes are snapped off with a tube tip breaker, just prior to use. Each tube comes with caps to protect the user from the sharp glass ends and to seal the tubes after sampling is complete, prior to sending them to the lab. Tubes are packaged 50 to a box, in order quantities up to 1,000.

Sorbent Tube Diagram

Sorbent TubesSorbent Tube HoldersThis unique patented system consists of a series of components which can be used to make up any of a wide range of different sorbent tube holders. That includes holders for single tube sampling or for multiple tubes manifolded together, with variable control of flow rate to each individual tube. These holders accept not only Sensidyne sorbent tubes but other standard sized industry tubes.

Tight Sealing, Visible Design

The quality construction of these holders features housings of clear plastic, allowing easy see-through inspection. In addition, each of the fittings at either end of the holder contains positive sealing O-rings in a double seal arrangement, eliminating any possible contamination of the sample by assuring absolute airtight integrity. They allow the sample tube to be flow-calibrated in place and also permit quick, easy reconfiguring of tube holder arrangements.

Single Tube Holder Kits

Kit comes with single holder, tubing, adapters and collar clip. Available for any of six different tube sizes. It can be ordered as a standard tube holder kit for constant flow control applications, or as a manifolded kit, which can also be used for variable flow single tube sampling, with a constant pressure (multi-flow) control in place.
