Testing Services:

Crystalline Silica Analysis


Clark provides Crystalline Silica analysis to advise companies if workers are within the permissible exposure limit (PEL) set forth by OSHA.

Samples are prepared and analyzed by X-ray Diffraction according to NIOSH 7500 to quantitatively determine the presence of Crystalline Silica. Analysis is reported as α-Quartz, Cristobalite, and Tridymite; also taking note of any interference in the analysis.

Clark provides sampling and analysis on both air samples and bulk materials. 

Clark is accredited by AIHA LAP, LLC for method: NIOSH 7500

What is Silica and Silicosis?

Metals/Elemental Analysis


Metal Fume and Metal Dust are commonly sampled during personal exposure assessments. Exposure may lead to irritation and in some cases disease; ultimately harming your nervous system and organs. Visit OSHA’s Permissible Exposure Limits for the elements of interest:https://www.osha.gov/dsg/annotated-pels/index.html

All samples are prepared by OSHA and NIOSH approved methods that include hot plate or microwave digestion. The samples are then analyzed to determine the airborne concentration of various metals by means of Inductively Coupled Plasma Spectroscopy (ICP) or Graphite Furnace Atomic Absorption (GFAA).

Routine testing include, but is not limited to:
  • Arsenic, Beryllium, Cadmium, Chromium, Lead, Nickel, etc.
  • Welding Fume Metals (13 metals) profile
  • Elemental Scan (>20 metals)
In addition to air samples, Clark offers elemental analysis on various bulk materials.

Clark is accredited by AIHA LAP, LLC for methods: NIOSH 7102, NIOSH 7302, and NIOSH 7304

What is Beryllium Exposure?

Organic Vapor Analysis


Air samples captured for Organic Vapors are prepared by NIOSH and OSHA methods and analyzed by Gas Chromatography (GC) or Ultra High Performance Liquid Chromatography (UHPLC).

We routinely provide analysis of the following Organic Vapors:
  • Various solvents - Benzene, Ethyl benzene, Toluene, Xylene, etc.
  • Ketones
  • Amines
  • Aldehydes
  • Polycyclic Aromatic Hydrocarbons/Polynuclear Aromatic Hydrocarbons
  • Alcohols
  • Paraffin Wax Fume
  • Total Hydrocarbons
Most Organic vapor sampling requires special handling; notably refrigerator/freezer storage. The Organics Lab also offers special project analysis tailored to meet clients' specific needs.

Clark is accredited by AIHA LAP, LLC for methods: NIOSH 1400, NIOSH 1500, NIOSH 1501,NIOSH 1550, NIOSH 5506, and OSHA 58

What is Organic Vapor Exposure?

Anion Analysis


Using various NIOSH and OSHA approved methods, our laboratory performs routine analysis of anions by Ion Chromatography to determine airborne concentrations.

The most common test requests for anions include:
  • Acid Fumes – Hydrochloric Acid, Nitric Acid, Sulfuric Acid, etc.
  • Sulfur Dioxide
  • Ozone
  • Fluorides – Particulate Fluoride and Gaseous Fluoride
  • Nitric Oxide and Nitrogen Dioxide
In addition, Clark provides the analysis of Hexavalent Chromium. accredited to AIHA LAP, LLC, we follow OSHA ID-215 v2.  According to this method, samples are prepared based on the operation being sampled: Painting Operations, Plating Operations, or Welding/Other Operations. Samples are unstable therefore requirement special handling.

Gravimetric / Extractions Analysis


We routinely perform Gravimetric analysis on filter cassettes. Doing so provides an air concentration of the particulate matter, by its overall mass captured on the filter with regard to the air volume sampled. Since gravimetric determinations are non-destructive, additional testing may be performed. Such add-on testing may include Silica, Metals, Hexavalent Chromium, or CTPV to mention a few.
  • Gravimetric – Total/Respirable Dust, Welding Fume Particulate
Another common test parameter includes Extractions. We routinely perform extractions on filter cassettes. The methods utilize such chemical solvents as benzene, cyclohexane, acetone, etc.

Common determinations include:
  • Extractions – Oil Mist, Benzene Soluble Fraction/Coal Tar Pitch Volatiles, Coke Oven Emissions
  • Methods NIOSH 0500, NIOSH 0600, and NIOSH 5042 are included in our AIHA LAP, LLC certification.
