Constant Performance Degassing Pump Product Suite
Description

This specification document highlights all the part numbers and components associated with theconstant performance degassing pump (CPDP) system. This intelligent, user defined control system,
when used with our film degasser 9000-2071, will provide more performance, increased efficiency andtighter control for HPLC instrument precision & reliability.
A new method of in-line HPLC degassing control is being introduced by characterizing theefficiency of a new, high performance flat film degasser at various applied vacuum levels. The
resulting calibration data produces a mathematical model of degassing channel performance thatallows the HPLC system to operate the vacuum degasser at the highest possible pressure(minimal vacuum level) to degas the mobile phase without affecting the performance of the HPLC
system. This, in turn, minimizes pervaporation and concentration changes in the mobile phase, as
well as reducing solvent vapor exhausted to the atmosphere. Because vacuum is adjusted using
pump RPM, higher pressure operation reduces pump wear. Degassing above the vapor
pressure(s) of the mobile phase also reduces concern for concentration changes across the fullflow rate range of the HPLC system.

Vacuum Pump with Constant Performance PCB

IDEX PN: 9000-2090 (Bottom Mount) & 9000-2091 (Side Mount)
Description

The Dual-Stage Pump (DST) with Constant Performance PCB is a vacuum control system for use
with IDEX Film Degasser chambers. The system includes a DST vacuum pump and a controller
PCB that operates in two modes.
1. Consistent with legacy degasser pumps, the control system will maintain vacuum levels ata user-defined setpoint (default 120mmHg).
2. Optionally, the Constant Performance algorithm allows the user to set a flow rate anddesired efficiency, from which the control algorithms will determine the nominal vacuum
level.

Constant Performance Vacuum Pump Specifications
Power Requirements
15-24 VDC @ 0.75 Amp max. (< 5 Watts consumption average)
Temperature• Storage: -29°C to 60°C
• RH: 15% to 85% noncondensing• Operating: 1°C to 60°C
Vacuum Flow Path Material
316L Stainless Steel, Polypropylene, PTFE, EPDM Rubber
Vacuum Accuracy±10mmHg from setpoint
Closed-Loop Control Setpoint
Default 120mmHg
LED Indicators or Optional Error Outputs
This section describes how the pump operation behaves during startup and into normal operation.
Error conditions are detected during startup and later during normal operation. Ambient pressure
is measured at startup and used when calculating vacuum efficiency. The system stores theambient pressure reading in non-volatile memory. Ambient pressure is updated when a significant
difference is detected from previously stored value.

The charts below depict the behavior of the vacuum system and the LED indicators. The examples
assume a setpoint of 120 mmHg.
In a normal pumpdown the LED flashes amber until it reaches setpoint + 30 mm. Then it flashes
green until reaching the setpoint. At the setpoint it will turn solid green. If it dips below the setpoint
it will flash green (not depicted).

If the pressure is unable to reach the setpoint after 10 minutes, the pump will stop and the LED willturn solid RED.

If the pressure reached the setpoint then later there was a vacuum loss, the LED will flash amberwhile it is 30 mm or more above the setpoint, flash green when less than 30 mm above thesetpoint, then solid green when it reaches the setpoint. If during a temporary vacuum loss it isunable to reach the setpoint for 6 minutes, the pump will stop and the LED will turn solid RED (notdepicted).

If at any time the pressure is more than 30 mm above the setpoint and the vacuum is not droppingat all, the pump will stop in a few seconds and the LED will turn solid RED. This indicates acatastrophic loss of vacuum with no ability to pump it down. This may be caused by an open
vacuum line. If this occurs at startup, the pump will run for a few seconds and then stop.
