Gel Free SPE Cartridge
Do you need a quick sample preparation method for gel and cream products?
Orochem offers new Gel Free SPE cartridges to remove carbomer from gel and cream products. There are two types: Gel Free LC SPE cartridges for sample preparation before injection to HPLC; while Gel Free GC SPE cartridges for GC samples. It is a one-step SPE method and no method development is required.
We have developed and validated organic impurities in hand sanitizer gel testing methods using Gel Free GC SPE cartridges.
