Mar 20, 2023 · The sample preparation step is very useful in obtaining precise and accurate results. Achieving a quickly performed, inexpensive, sensitive, and accurate analytical approach for measuring extremely small amounts of a dangerous compound such as mycotoxin, while posing environmental issues, has always been crucial and important. In this paper, fabric phase sorptive extraction (FPSE), a novel
Jul 11, 2017 · In a syringeless filter, the filter membrane, pre-filtration chamber, post-filtration storage vial, and cap are all part of one device (Fig 2). This design streamlines HPLC sample prep and minimizes the number of laboratory consumables. Filtration with a syringeless filter can be performed three times faster than with syringe filters. Using a
“Integrity testing of the filter(s) can be performed prior to processing, and should be routinely performed post-use. It is important that integrity testing be conducted after filtration to detect any filter leaks or perforations that might have occurred during the filtration.
