Get PriceLaboratory sample preparation is the process of converting the sample received at the laboratory into a homogeneous material suitable for analysis. This process generally involves drying and/or grinding. Most forage samples received at a laboratory fall into one of the following categories:
Get PriceThe reference ranges for your tests can be found on your laboratory report. They are typically found to the right of your results. If you do not have your lab report, consult your healthcare provider or the laboratory that performed the test(s) to obtain the reference range.
Get PriceSolidphase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid or a solid , which extracts different kinds of analytes (including both volatile and nonvolatile) from different kinds of media, that can be in liquid or gas phase.
Get PriceAs head hairs are routinely compared in a forensic laboratory, it is important to obtain suitable known samples from suspects and victims and possibly from other individuals (elimination samples). The known sample should contain a random sampling of hair from different areas of the scalp.
