We know if you can’t filter your real world samples, there’s no reason to invest the time and effort to perform EPA SPE Methods in-house. As such, we encourage you to:
(1) Send us your difficult samples to evaluate,
(2) Request samples of Xenosep SPE Filters for your current equipment, or
(3) Buy a Xenosep Extraction Apparatus and try it risk-free in your lab for 30 days.
If the samples can’t be filtered in a timely fashion or the QC criteria achieved within this timeframe, simply return the extraction apparatus with any unused filters and owe nothing - it’s that easy.
