The GC is telling us that the front inlet pressure is 'Not Ready' is there a chance there is a leak in the inlet somewhere after the maintenance was performed?
Can the inlet hold pressure? If it can't hold pressure or does have a leak it will stop the…
Hello cpostigo ,
This error will occur if the batch has not been analyzed and there is no calibration curve available for your targets. The entries do appear to be accepted, and the calculation will be performed once the batch has been fully analyzed…
Hi, DP stands for Drug Product (I need to determine EtOH in a drug product not in a drug substance DS).
I'm loading 3 mL of sample in vial size 20 mL. The concentration of EtOH 4 mg/mL.
Yes of course, three replicates of three separate vials (same…
