一般描述

Solid phase extraction apparatus uses glass vials or tubes for sample collection and concentration. Some sorbents require large desorption volume than small SPE cartridges in such case SPE tubes were used.

应用

Empty SPE Tube (no frits) was coupled with closed-face polystyrene cassette containing glass fibre filters in a method to reduce the interference from vapour solvent caused in vapour fraction, during mist sampling and analysis, in an experiment conducted to study the occupational exposure to mineral oil metalworking fluid (MWFs) Mist.

特点和优势

当与固相萃取管接头配合使用时，在处理时固相萃取空管可堆叠在标准固相萃取小柱的顶部。空的固相萃取小柱可用作储液器，以容纳更大的取样量。
