SPB-辛基 气相色谱柱:
Application: The low polarity of this column approaches squalane, making it substantially less polar than that of the widely used non-polar poly(dimethyl siloxane) columns. This column offers unique selectivity compared to non-polar and intermediate polarity columns, and can be used for confirmational analyses of PCB-containing samples.
USP Code: None
Phase:
* Bonded
* Poly(50% n-octyl/50% methyl siloxane)
