Passive Inlet Valve Upgrade Kit for standard Agilent 1100/1200 pump replaces AIV
The Agilent 1260 quaternary pump has done away with the expensive combination of the Active Inlet Valve (AIV) body, and it's internal replacement valve cartridge. Both components have been replaced with a single Passive Inlet Valve (Agilent p/n G1312-60066). The original dual component AIV can be challenging to troubleshoot, has a higher combined failure rate than the PIV, and costs a lot more to replace.
GLTS has created a kit that allows the new PIV (must be purchased separately by Customer from Agilent, part number G1312-60066) to be installed on standard Isocratic, Quaternary, or Binary pumps. It includes a solvent feed tube that fits the new Agilent PIV, and a diagnostic plug that plugs into the AIV receptacle in place of the original AIV's wire and plug. The diagnostic plug also gives valuable troubleshooting feedback and comes with a diagnostic card to allow a user to determine if pump irregularities are due to plunger/seal, valve, or leak issues.
Each pump head upgraded will require 1 PIV valve from Agilent (p/n G1312-60066), and 1 GLTS PIV Upgrade Kit. Isocratic and Quaternary Pumps require 1 PIV valve and one GLTS PIV Upgrade Kit. For a Binary Pump, you can upgrade one or both pump heads (both would require 2 PIV valves and 2 GLTS PIV Upgrade Kits).

GLTS Damper Adjust Module solves "Pressure Signal Missing" error from 79835-60005
The "Pressure Signal Missing" error is generated on standard 1100 & 1200 LC pumps when the Main Board reads too low a signal from the Damping Unit pressure sensor (79835-60005) as a "zero" pressure value is read before the pump is initialized. The Main Board will tolerate a slight drift towards a negative reading and still display 0.0 bar, but if the zero pressure signal is internally interpreted as reading below -3 bar, the pump logic returns the "Pressure Signal Missing" error and locks out the pump operation. The repair strategy has been the replacement of the expensive Damping Unit.
The GLTS Damper Adjust Module is designed to be installed in series with the cable from the Damping Unit that normally goes directly to the pump's Main Board. It translates the "zero" signal value with an adjustable setting so that the signal can be brought back into an acceptable range, but at a significant cost savings over replacing the Damping Unit. There is also a second pre-calibrated adjustment that also allows for adjusting the scaling of the Damping Unit signal, so that calibrating the pressure signal with a mid or high pressure standard is also possible.
