Examples of Cosmetic Products Tested Protheragen-ING's microbiological testing services include a comprehensive portfolio of cosmetics and personal care products. We can also provide microbiological analysis of raw materials used in product development. ...
Use of cryoprotectant agent (CPA): Certain chemicals can be used to help the cryopreservation process. CPAs are added to the sample to reduce the freezing point of the sample and slow the cooling rate. This will reduce the risk of ice formation within the sample that can lead to damage. Freezing: There are different methods of freezing that can ...
After the customer received our samples and personally did the sample quality inspection, the customer accepted the more cost-effective PET Filament geotextile. ...
While even a moderate lack of clarity is noticeable to even casual observers, the average person would probably describe a sample of such water as “cloudy” or ...
The best method of determining exposure is actual sampling while he/she is at work, play or home. Miniaturization of sampling equipment now allows samplers to be placed almost anywhere including on the person. ...
The technology for doing so is similar but different instruments are available for every application. Ashtead supplies personal air sampling pumps when it is necessary to conduct compliance monitoring, or when the identification and measurement (in a laboratory) of a specific dust type, such as RCS, is required. ...
Once the exposure testing period is complete, the sample can be sent to a laboratory for analysis. The proper person to do the sampling is referred to as an industrial hygienist—or a specially trained safety person. ...
A typical day includes a range of dust assessments, from wood, welding fumes, quarry dust, and respirable crystalline silica. He undertakes personal exposure monitoring across the workforce to control exposure levels and where necessary, provides recommendations with preventative health measures to control any hazards from dust, noise and vibration. ...

Monitoring might be conducted in a work space, or personal sampling might be undertaken in order to assess the exposure of an individual over an entire shift. Personal Sampling Pumps represent the preferred method for workplace exposure monitoring where it is necessary to demonstrate regulatory compliance or where legal dispute ...
Easy to read and search through, the Waste Free Kitchen Handbook can tell you how much food to make per person, what a sample meal plan looks like, and how to turn that old cabbage into Easter egg dye. ...
Workplace monitoring solutions for dust monitoring include personal sampling pumps to monitor employees’ personal exposure to dust and real time dust monitors to assess the occupational risks completed by a walk through survey and checking existing controls. ...

The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air. The most common devices for sampling isocyanates are impingers and impregnated filters. Impingers are the least desired for personal ...
Small Samples 1ml to 10ml – tamper evident tubes Even with small samples you can ensure your samples are safe, try these tamper evident microtubes for 1 to 1.5ml sample sizes, or the slightly larger transport tubes with security caps for 5ml up to 10ml samples. Both types still use the same principle ...
According to the abstract, overall, elemental carbon personal breathing zone and area time-weighted average samples were below the NIOSH recommended exposure limit (REL) of one microgram per cubic meter (µg/m3) elemental carbon as a respirable mass (96 percent were less than one µg/m3 at the respirable size fraction), while 30 percent of the inhalable ...
Service performed: Industrial hygiene monitoring at a pharmaceutical manufacturing facility Summary: Our environmental staff performed testing and consulting to determine employee exposure levels to hazardous chemicals at a large manufacturing facility. Engineering controls and personal protective equipment were also evaluated for its effectiveness during the manufacturing ...
The study examines the economic growth of gateway communities in the Amvrakikos Wetlands National Park with the use of a structured questionnaire and through personal interviews. Simple random sampling was used as a method. The case study constitutes an approach used to examine local people’s views concerning the various characteristics of the broader area, their ...
Researchers measured the silica levels of more than 100 personal breathing zone samples at fracking sites in five states, finding levels above the Occupational Safety and Health Administration's permissible exposure limit (PEL), NIOSH's recommended exposure limit (REL), and the American Conference of Governmental Industrial Hygienists threshold limit value (TLV). ...
This study uses data collected from a 2005–2006 in–person sample of trekkers in Nepal and a contingent valuation survey questionnaire. ...
Following a competitive tender process, the Australian Department of Defence has taken delivery of 180 TUFF personal air sampling pumps and 180 CEL-350 dBadge personal noise dosimeters from Casella CEL (www.casellameasurement.com; 01234 844100), leading global specialist in industrial hygiene and occupational health monitoring equipment. ...
