SIB Labs, biojalostuksen pyrolyysinesteitä

HPCCC (High Performance Counter Current Chromatography)  

Counter current chromatography is a mode of liquid chromatography. There are two insoluble liquids without a solid column. One liquid serves as stationary phase and the other as mobile phase. Stationary phase is kept immobile with centrifugal force.

SIB Labs kemiallinen analyysi, 2D-kaasukromatografi-massaspektrometri

2D-GC-MS (2-Dimensional Gas Chromatography Mass Spectrometry)  

2D-GC-MS is used for identifying volatile organic compounds from various samples. Compared to basic GC-MS systems, selectivity and sensitivity are improved due to second column and Zoex thermal modulator. AOC-5000 sampling robot and Optic-4 injector allow versatile sampling options for gas, liquid and solid samples.

 

SIB Labs biojalostus, mikro-kaasukromatografialaite

Micro-GC (Micro Gas Chromatography)  

Micro-GC is suitable for analysis of basic gases (H, N, O, hydrogen sulfide, CO2 and CO, He, and Ne) from air and process gases. Also hydrocarbons (C1-C7) can be analysed.
