sample needle
The Versa uses a 1-stage sample needle to displace sample
from the vial to the sample loop.
floW restrIctor
The Versa uses a 100mL/min flow restrictor to provide
standby flow and pressurization flow. When the system
pressure is set to 18psig, the standby and pressurization
flow measured out the needle is approximately 50mL/min.
caroUsel tray
The 20-position carousel tray is removable from the
carousel drive assembly; the tray can be removed without
the vials.
Gas Inlets and oUtlets
transfer line
The Transfer Line is the interface between the GC and the
Versa. Carrier gas makes a passive current through the
Versa and returns unchanged to the GC through the
transfer line. GC carrier gas is typically controlled through
the GC.
Carrier Gas is helium (or nitrogen) with a high degree of
purity, used to flush volatile organic analytes through the
transfer line back to the GC. Carrier gas enters the back
of the Versa through the heated transfer line. Carrier gas
back flushes through the sample loop and carries volatile
organic analytes over to the GC.
pressure sample Gas Inlet
Pressure sample gas (ultra-high purity helium or nitrogen)
flows through the Versa System to pressurize the vial and
sweep clean the system between samples. The gas enters
the unit through the back panel in the blue 1/8” tubing
labeled “Pressurize Gas”. Refer to the Method Development
section of this manual to determine the proper flow rates
and pressures for your specific application.

Introduction • Page 1-10
Never connect a flammable gas
(such as hydrogen) as the gas
supply to the Versa. Venting of
this gas in the standby creates
an explosion hazard.
