The Diablo MS Sensor software is designed to allow simple and flexible acquisition and display of real-time process data using the Agilent Technologies 5977 MSD and other kinds of instruments and sensors like pressure and flow meters. You can create calibrated signals, enter user-defined formulas, and trend plot those results in real time. The MS Sensor software is included with every Diablo 5000A Real-Time Gas Analyzer.
Agilent Technologies 5977 Mass Selective Detector
The Agilent Technologies 5977 Mass Selective Detector (MSD) is a high-performance bench-top quadrupole mass spectrometer. The MS Sensor software also enables the older 5973N and 5975 MSDs to perform continuous process analysis.
Instrument Configuration
The MS Sensor software provides a simple interface for user configuration. The user only needs to specify the masses of interest and the proper tune file to configure the 5973/75/77 for a run. The software automatically sets other instrumental parameters. Advanced users can easily override the default parameters using the "Advanced" dialog.
Advanced Configuration
The Advanced Configuration dialog allows advanced users to override the default instrument settings for the 5973/75/77 MSD:
Instrument Diagnostics and Tuning
The MS Sensor software provides a customized version of the 5973/75/77 MSD manual tune window. The manual tune window is used to tune the MSD, vent or pump down the vacuum system, and perform instrument diagnostics. The 5973/75/77 MSD can be tuned using one of the autotune algorithms, or it can be manually tuned by an experienced user.
The MS Sensor software provides an exclusive hydrogen tune function that optimizes the response of the 5973/75/77 for low-mass gases like hydrogen.
Data Analysis
The 5973/75/77 instrument driver can be configured to create a "data.ms" file that contains the raw mass-spectral data acquired during a run. This file can be loaded directly into the Agilent Technologies MSD ChemStation data analysis module to perform library searches, spectral manipulations, and other data analysis functions.
MSD ChemStation Requirements
The 5973/5975 instrument driver requires that version D.00.00, or later, of the Agilent Technologies MSD ChemStation be installed and operational prior to installing the MS Sensor software.
MassHunter GC/MS Acquisition Requirements
The 5977 MassHunter instrument driver requires that version B.07.00 SP1 or later of the Agilent technologies MassHunter GC/MS Acquisition software be installed and operational prior to installing and using the MS Sensor software.
Other Instruments
The MS Sensor software uses an interface architecture that allows data to be collected from several kinds of instruments. A driver has been written for each instrument described below.
Supported Instruments
The following table lists the instrument drivers that are currently provided with the MS Sensor software.
| Instrument | Description |
| Diablo MS Simulator | A simple simulator that generates random abundance values over a specified "mass range". This "instrument" driver is used for testing, demonstration, and training purposes. |
| Agilent 5973N, 5975, or 5977 Network MSD | The Agilent Technologies 5973N, 5975, or 5977 Mass Selective Detectors (MSD) using the Ethernet/Network interface. |
| MKS 651C Pressure Controller | Reads pressure data from an MKS Instruments 651C Pressure Controller using a serial interface. |
| MKS PR4000 Pressure Controller | Reads pressure data from an MKS Instruments PR 4000 Pressure Controller using a serial interface. |
| MKS PDR2000 Pressure Controller | Reads pressure data from an MKS Instruments PDR 2000 Pressure Controller using a serial interface. |
| Diablo MPValve Multiposition Valve Control Software | An instrument driver that integrates the MS Sensor software with Diablo's MPValve 3.0, multiposition valve controller software for VICI multiposition, stream-selection valves.Important: The MPValve software must be licensed separately from the MS Sensor software. |
It is possible for other instruments to be added to the MS Sensor process analysis software via a custom driver developed by Diablo Analytical, Inc. Please contact Diablo for more information.
