Tj. Buckley et Ka. Gillis, ALL-METAL COLLECTION SYSTEM FOR PREPARATIVE-SCALE GAS-CHROMATOGRAPHY - PURIFICATION OF LOW-BOILING-POINT COMPOUNDS, Journal of chromatography, 702(1-2), 1995, pp. 243-250
We describe a purification system based on a commercial preparative-sc
ale gas chromatograph with a custom-designed condenser, collector, and
fraction handling system. In our fraction collector design, all the w
etted surfaces were either 316 stainless-steel or nickel. The collecto
rs and the integrated gas-handling manifold were designed to be used d
own to liquid nitrogen temperature and up to 7 MPa of pressure to acco
mmodate low-boiling-point compounds, such as refrigerants. The design,
operation, and performance of this apparatus are presented.
