网页2015年11月16日 · I heard that LC vials with non slit septa gives OOS results, if the vials are filled to the neck, it creates vaccum or back pressure. The issue is not with the septa but with overfilling the vial. Slit septa leak around the needle while the sample is being withdrawn, so the headspace stays at atmospheric pressure.
MS® HPLC and GC sample vials offer a number of benefits over the standard straight glass sample vials. The flared end assists the needle into the vial enabling the loading of liquid samples easier. This flared end also allows the vial to be easily inserted and removed from the end of the probe using tweezers without breaking the glass due to the vial’s superior strength.
