How SPE disks differ for hexane extractable material
By Biotage
The quality of the solid phase disk used for extraction is key to the success and ease of an analysis. Pacific® Premium Oil & Grease SPE disks from Biotage for Method 1664/ISO 11349 meet all Initial Precision and Recovery (IPR), Method Detection Limit (MDL) and Ongoing Precision and Recovery (OPR) limits specified by the US EPA, while saving the lab extraction time and solvent volume. Both 47 and 90 mm disks are fast-flowing and have a high-retention capability, which increases efficiency without compromising recoveries.
A number of tests were performed, comparing oil and grease disks from Biotage (Pacific® Premium and Pacific®) with a variety of other competitor’s disks, available commercially. Twelve disks of each type from a single batch were tested and to make the comparison as valid as possible, the disks were run using the same method conditions on the same equipment. Automation of the SPE process using the SPE-DEX® 3000XL (Horizon Technologies, now part of Biotage) to apply the sample and elute the hexane extractable material provided the most consistent results.
