Usata per passivare il tuo Sistema LC prima di effettuare la tua prima analisi se:

(a) stai analizzando composti fosforilati o altri composti polari conosciuti per le loro proprietà chelanti o che interagiscono con ioni metallici nel tuo LC (es: glifosato)

e anche se

(b) hai componenti in acciaio inox nel percorso di flusso del tuo strumento.

Our high-quality air monitoring gas calibration standards are provided by Spectra/Linde and Airgas (formerly Scott/Air Liquide gas)—meeting lab requirements for two separate sources of calibration standards.

Note: Actual cylinder pressure may vary due to loss from quality testing procedure.
