Why doesn't the purge flowrate agree with the setting on my Shimadzu Laboratory Equipment?
If the purge flowrate does not agree with the setting on your Shimadzu Laboratory Equipment, ensure that the column inlet pressure is sufficiently high. Also, verify that [I time] = "10", [P term] = "50", and [I term] = "100". If these values are not correct, enter the correct ones and press the pf4 key to write them in the ROM.
What causes the pressure to be higher than the setting in split mode in Shimadzu GC-2014?
If the pressure is higher than the setting in split mode for your Shimadzu Laboratory Equipment, check that the setting is within the range of settable pressures/flowrates for AFCs. Also, verify that a blind has not been erroneously attached to a split vent. Additionally, confirm that [I time] = "1", [P term] = "100", and [I term] = "150"; if not, enter these values and press the pf4 key to write them in the ROM.
Why is the inlet pressure lower than the setting in split mode on my Shimadzu Laboratory Equipment?
If the inlet pressure is lower than the setting in split mode on your Shimadzu Laboratory Equipment, check for leaks using a snoop. Ensure the source pressure has reached a sufficient level. Also, verify that the setting is within the range of settable pressures/flowrates for AFCs.
What to do if ignition is not possible in Shimadzu GC-2014 Laboratory Equipment (FPD)?
If experiencing ignition problems with the FPD on your Shimadzu Laboratory Equipment, the igniter filament may have burnt out. If so, replace the igniter.
What causes the total flowrate to be higher than the setting in Shimadzu Laboratory Equipment?
If the total flowrate is higher than the setting in your Shimadzu Laboratory Equipment, verify that [I time] = "1", [P term] = "15", and [I term] = "40". If not, enter these values and press the pf4 key to write them in the ROM. Also, check the [Offset] and [Gain] values for the flowrate. If the gas continues to flow into the carrier line even when the power is off, the AFC may need replacement.
What to do if ignition is not possible in Shimadzu GC-2014 Laboratory Equipment (FID)?
If experiencing ignition issues with the FID in your Shimadzu Laboratory Equipment, the igniter filament may have burnt out, requiring replacement. Another potential cause is a fault in the igniter circuit; check the voltage at both ends of the connector (between 1 (+) and 2 (-) of CN2) during ignition with the igniter filament connected. Lastly, the nozzle might be clogged with sample or graphite ferrule residue; clean (using, for example, CLEANING WIRE, 201-79229-01) or replace the nozzle.
How to reduce noise in Shimadzu Laboratory Equipment (FID)?
If you're experiencing a lot of noise (high level) with the FID on your Shimadzu Laboratory Equipment, the collector might be dirty. Try removing the igniter and cleaning the metal portion of the collector with a liquid like hexane. Alternatively, the H flowrate may be fluctuating, in which case you should replace the APC.
How to resolve unstable inlet pressure in Shimadzu GC-2014 Laboratory Equipment?
If the inlet pressure fluctuates (unstable) in your Shimadzu Laboratory Equipment, first check that [I time] = "1", [P term] = "100", and [I term] = "150". If not, enter these values and press the pf4 key to write them in the ROM. If using a glass insert for WBI, adjust the column insertion length to approximately 15 mm (normally 34 mm). Additionally, set the inlet pressure to 0 kPa and the total flowrate to 400 mL/min to check the flow-line resistance of the split line. Finally, ensure there is no clogging in the purge-line flow line.
