to 50 °C in 4.0 min (3.5 min with
oven insert accessory).
• Ambient rejection: < 0.01 °C per 1 °C.
Electronic Pneumatics
Control (EPC)
• Compensation for barometric pressure
and ambient temperature
changes is standard.
• Pressure has typical control of
±0.001 psi for the range of 0 to
150 psi. Pressure setpoints may be
adjusted in increments of 0.001 for
the range 0.000 to 99.999 psi;
0.01 psi for the range 100.00 to
150.00 psi.
• User may select pressure units as
psi, kPa, or bar.
• Pressure/flow ramps: Three
maximum.
• Carrier and makeup gas settings
selectable for He, H2, N2, and
argon/methane.
• Flow or pressure setpoints for each
inlet or detector parameter with both
