Designed for moderately dirty samples, Xenomax Solid-Phase Extraction (SPE) Filters for EPA Method 1664A provide maximum recovery, speed and particulate loading capacity. Chemically treated with a proprietary reverse phase adsorbent, triple layer borosilicate glass Xenomax SPE Filters (47mm) can filter the 40 mg/L EPA PAR standard in approximately 20 seconds with similar filtration times for 1-L NPDES-type samples. Xenomax SPE Filters provide maximum analyte recovery, particulate loading capacity and processing speed when used with Xenosep SPE Glassware.
