Accurate, Cost-Effective Chemical Analysis and Monitoring

ABOUT US

For many years industrial hygiene sampling was done using a mechanical sampling pump. For many organic vapors, the air would be pumped through a charcoal tube. The pump needs to be calibrated before and after the sampling period. If the flow rate of the pump is too high, the vapor to be sampled will break through the sampling tube and be lost. Often two sections of charcoal are used. Then two analysis would be needed to obtain reliable results. This method is expensive and cumbersome, especially for monitoring personal exposure. In 1976 the company Advanced Chemical Sensors was founded by Laurence D. Locker, (Ph.D., M.I.T.) to develop improved methods to measure exposure to toxic vapors regulated by U.S. occupational safety laws. The technique of passive monitoring was developed to eliminate the need for a mechanical pump to collect the air sample. The pump is replaced by a solid adsorbent separated from the ambient air by a porous membrane. This device acts like a pump, but with no moving parts. The cost saving and the ease of use gives this method wide application to measure employee exposure and room concentrations of many chemicals. A U.S. Patent was issued to Dr. Locker in l982. A subsequent patent was issued in Japan in 2001.

The products are used in health care facilities, by government agencies and by many of the largest industrial corporations. The Company's products are available in the U.S., South America, Europe and several locations in the Far East.

We look forward to your used of our products. Followings are some of the recent accomplishments that should reaffirm our belief that we offer the most cost effective and lowest cost method to accurately measure personal exposure and room concentrations of toxic vapor.

  • The monitoring badges won a Prize for Innovation at the Paris Intermedica Exposition in 1996.
  • The laboratory has been accredited by American Industrial Hygiene Association Laboratory Accreditation Programs, LLC (AIHA-LAP, LLC). This comes after evaluation of our quality assurance procedures and after an on-site inspection.
  • The American Dental Association (ADA) has evaluated the accuracy of nitrous oxide monitor badges. Their data indicates that our monitoring badge is accurate. Monitoring badges from two other companies are found to be not acceptable.
  • In January, 2000 and again in July, 2001 an independent validation study by a Japanese government agency found that our Formaldehyde/Glutaraldehyde Vapor Monitor badge and the ones for benzene, toluene, xylene, and styrene are significantly more accurate than required by US OSHA standards.
  • In August 2001, ACS quality assurance procedures were examined on-site by an inspector from New York State Dept. of Health as part of the renewal of our Environmental Laboratory Approval Program accreditation.
  • In February 2002 we were granted a Patent by the Government of Japan for technology used in the monitoring badges. The supplements a previous U.S. Patent. We have participated in Proficiency Analysis Testing Programs for more than 15 years, as part of the accreditation by the American Industrial Hygiene Assoc. Of forty-four samples with unknown concentrations submitted to us for analysis so far in 2003, we have received and “A†rating for all forty-four.
