6890 GC Lit Offset parameter in Empower software

Hello-In Empower 2 FR 5, Waters added control of the Agilent 6890 GC FID and FPD Lit Offset parameters. The Lit Offset value determines the threshold for automatic reignition of the detector's flame. When a new instrument method is created in Empower 2 FR 5, the FID (or FPD) Lit Offset value is set to 0.0 pA by default . However, a non-zero Lit Offset value is required in order to trigger automatic flame ignition if the flame should happen to go off during the course of a running sample set. Otherwise, the detector gases would continue to flow even if the flame was off. The recommended default setting for Lit offset is 2.0 pA. An enhancement request - SCR #44424 - was submitted to change the Lit Offset default setting to a non-zero value. The enhancement is being considered for a future update to Empower 2.Waters would like to get your input regarding another possible change, to require a non-zero value for Lit Offset. Do you feel that it is useful to have the option of setting a zero value for Lit Offset, or would you prefer that the minimum allowed value be raised, perhaps to 0.1 pA?If these changes are implemented, new 6890 GC instrument methods would then use the new Lit Offset default value and also disallow a zero value entry.Would you be in favor of implementing both of these proposed changes in Empower software? How would the changes affect any of your SOPs? Your input and any related suggestions are greatly appreciated. Jagat AdhiyaGlobal Software Support, Waters
