2022年11月10日 · Tuning the Agilent GC/MSD with EI sources, requires the use of perfluorotributylamine (PFTBA). The calibration vial will be depleted eventually due to regular use. This article explains how to refill the calibration vial. Steps to follow: Materials required. To Refill the Calibrant vial. Stop any tuning or data acquisition.

This manual contains information for operating and maintaining the Agilent 5975 Series Gas Chromatograph/Mass Selective Detector (GC/MSD) system. 1 “Introduction” . Chapter 1 describes general information about the 5975 Series MSDs, including a hardware description, general safety warnings, and hydrogen safety information.

2023年8月2日 · 1. See the article How to check the Air and Water Background on an Agilent 5975 and 5977 GC/MS and work through the Manual Tune method to Step 10. 2. Double click the PFTBA field or slide the PFTBA slider so that the PFTBA calibration valve in …

2023年8月2日 · Air and Water background is determined relative to the PFTBA m/z 69 peak abundance. PFTBA m/z 69 peak abundance is typically ~500,000 counts for the tune report after a full autotune of a 5975 or 5977 MS (atune.u). Air background is …

We have produced this list of the most commonly ordered supplies and parts for the Agilent 5973, 5975, and 5977 series GC/MSD. Keep this list so you can quickly find the supplies you need and minimize instrument downtime. Having trouble selecting the appropriate aperture diameters for the Agilent 5977A/B series ion sources?

Page 3 This manual contains information for operating and maintaining the Agilent 5975 Series Gas Chromatograph/Mass Selective Detector (GC/MSD) system. “Introduction” Chapter 1 describes general information about the 5975 Series MSDs, including a hardware description, general safety warnings, and hydrogen safety information.

Introduction The 5975 Series MSD The 5975 Series MSD is a stand-alone capillary GC detector for use with Agilent Gas Chromatographs (Table 3). The MSD features: • Local Control Panel (LCP) for locally monitoring and operating the MSD • …

To perform a tune or autotune, MS systems introduce a volatile calibrant and adjust the MS parameters to meet some criteria, such as the abundances of certain calibrant ions. Historically, that is how the 597X Series of instruments have been tuned. (Software allows the user to change or adjust these tuning targets through the Tune Wizard.)

Chapter 1 describes general information about the 5975 Series MSDs, including a hardware description, general safety warnings, and hydrogen safety information.

As PFTBA passes through the MS, the instrument optimizes several settings to obtain the maximum detector response (counts per second) for selected ion fragments of the tuning compound. Results from one of the most common brands on the market (Agilent 5975C) are shown in Figure 7.1.
