Torrent Laboratory, Inc. Uses Efficient Wipe Sampling Process in its Environmental Laboratory to Determine the Level of Surface Contamination

The purpose of an environmental laboratory is to test for harmful and unknown substances in the environment. Torrent Laboratory, Inc. delivers dependable results in drinking water testing, soil vapor testing, ambient air testing, and ground water testing. They perform all testing in their material testing laboratory. In order to correctly conduct these tests, the sample collection process must be followed exactly. Bottles for water samples, other special containers, and wipes are used to test all samples in the material testing laboratory.

Wipe sampling is the process used to estimate the amount of contamination on different surfaces. There are a number of wipe sampling methods and the method chosen depends entirely on the contaminant of concern. A problem with wipe sampling is that it can be difficult to interpret results. Filter paper that is dampened with a type of solvent is often used, and this wipe sample can and does yield the mass of the analyte. However, there is no simple way to convert this mass into a concentration per unit area, and there is no good way to compare results from different wipes. Also, the variations between surface types (for example, a surface's texture) make it next to impossible to judge the efficiency of the wiping process. Thus, it is very important that the material used for wiping be the correct material for the area of interest. The environmental laboratory must engage in extreme caution during testing and when determining final results.

Once the correct wipe sample has been determined, validated, and properly collected, it is delivered to the material testing laboratory. The wipe sampling technique can be a trustworthy and sure way of assessing the level of contamination that may exist if it is done properly. Torrent Laboratory, Inc. operates under teh assumption that in order to get an accurate representation of the contaminant, samples should be wiped first in a "back and forth" motion and then in an "up and down" motion. The professionals at Torrent Laboratory also insist that the correct solvent be used on each wipe and that a separate wipe should be used for each test because a separate wipe is required for each method. For all samples, whether they are for drinking water testing, soil vapor testing, ambient air testing, ground water testing, or wipe samples, there are certain standards that must be followed:

* All containers used must be properly sealed and labeled with non-removable marking and water-resistant labels

* All samples should be kept at 4C unless instructed otherwise. The samples should not be frozen until they reach the environmental laboratory or until the samples are picked up by the environmental laboratory courier.

* Samples should be packaged carefully to avoid being damaged during transport.

* All laboratory submission forms should be completed and included with the samples.

* Arrange for pickup or delivery as soon as possible after taking the sample to avoid hold time violations.
