Need a conversion factor in a hurry? Want to see where the sample goes in a
capillary GC split injection? Visit the Expert Center on the Restek website.
Located in the "Info. & Support" menu, the Expert Center includes a tremen-
dous variety of useful information. Our
calculators
, for example, are
extremely handy tools. Use the Backflash Calculator to determine how much
sample in a particular solvent you can introduce into a capillary inlet liner
without the expanding sample backflashing into, and contaminating, the sys-
tem. Use the Pressure Calculator to quickly interconvert among the various
measurements of pressure: psi, atm, kg/cm
2
, Torr, inches Hg, kPa, bar.
The
animations
of capillary GC injection techniques and operation of a 6-
port HPLC valve enable you to view these processes, and help you appreciate
the benefits, and potential problems, associated with each. The subjects in the
Expert Center include:
Troubleshooting
Chromatogram Archive
Optimization Calculators
