When ordering sample media from us, using the “Part Number” from the Directory ensures that you get exactly what you’re looking for. If you’re not sure, simply look in the Directory for the analysis you wish to do and look in the column “Recommended Media”. This will tell you Analytics’ Part Number and in many cases, the SKC part number. Did you know that many of our media is available at no additional charge if you send the samples back to us for analysis. Just look for the “*NC” under the Price column. Some media will be shipped overnight automatically since they need to stay cold, such as the UMEx 100 badges.

Hexavalent Chromium Sampling Technical Bulletin

Exposures to Hexavalent Chromium

Produced by many industrial processes, Cr(VI) is the (+6) valence state of the element chromium. It is known to cause cancer, and also targets the respiratory system, kidneys, liver, skin and eyes. Chromium in steel alloys is a major source of worker Cr(VI) exposure during “hot work” like welding, especially on stainless steel. Common CrVI compound uses include pigments (dyes, paints, inks, plastics, etc.), anti-corrosive agents in surface coatings, and as chromic acid in electroplating. Worker protection requirements are addressed in specific OSHA hexavalent chromium standards which may be accessed below.

Semi-Volatile Compound Change Notification

Compound bis(2-Chloroisopropyl)ether has been changed to 2,2′-oxybis(1-Chloropropane). This change is due to an update in the TNI 2009 standards. Our VELAP certification has been revised to reflect this change. For the immediate future, all reports will reflect both names until customers can update any database issues the name change may cause. Please call Customer Services at 800-888-8061 with any questions or concerns.

– Sampling Using Filters

Filters include glass fiber filters, Teflon filters, mixed cellulose ester membranes, polyvinyl chloride filters, and treated filters and pads.
Sampling with filters can be done open or closed faced. Open-faced sampling is done with three(3) piece cassettes with just the top of the cassette removed. Closed-faced sampling is performed with only the buttons removed from the cassette. Open-faced sampling is used in situations where even dispersal of the analyte over the filter is desired, such as in asbestos sampling or on certain coated filters such as for isocyanate sampling. Closed-faced sampling is performed in most cases of particulate sampling, which deposits the analyte near the center of the cassette. Click here for full instructions.

– Solid Sorbent Tube Sampling

Solid sorbent tubes include large and small charcoal tubes, porous polymer tubes such as XAD and XAD-7, large and small silica gel tubes, DNPH (dinitrophenyl hydrazine) tubes, Orbo tubes, Porapak Q, Tenax tubes, Firebrick tubes, Hydrar tubes and Florisil tubes. Sampling should be performed in the following manner: Click here for full instructions.

OSHA Issues Temporary Enforcement Policy for Confined Spaces in Construction

OSHA issued the Confined Spaces in Construction final rule on May 4, 2015, but becomes effective August 3, 2015. This is a temporary enforcement policy will be in effect for 60 days. The full enforcement of the new standard will be in effect October 2, 2015. This is to give additional time to train and acquire the equipment necessary to comply with the new standard. For more information, click here for the OSHA Trade News Release.

Passive Monitoring Sampling

Do you need to perform passive monitoring sampling without the use of special equipment or the need for expert knowledge? These badges may be for you.

SKC and 3M brand passive monitors can be used for the determination of organic vapors in air. Passive samplers are small “badges” that collect organic vapors without the use of a pump. Individual chemicals simply diffuse from the atmosphere into the sampler at a fixed rate. These scientifically validated passive samplers meet OSHA requirements and are a viable alternative to active sampling.
