Mass Spec Software Tools - from SIS
SIS has written the following online programs as tools for
use by the mass spec community. The programs are designed to be
used on line (no need to download). If you have any additional suggestions
on how to improve these programs or additional programs that
should be made available, we
would like to hear from you.
Isotope Distribution Calculator and Mass Spec Plotter
Just type in the chemical formula and this
program will calculate the intensity of each
mass isotope in the species.
The analysis can be done in both high and low resolution.
The program can also plot either
calculated or manually inputted isotopic distributions,
and the mass range can be scaled for better view the data.
- Mass Spectrum Generator
Just type in the mass spec peaks and their relative intensities
and this program will generate a mass spectrum plot. The plot
mass range can then be scaled to better view the relationship of
- Exact Mass Calculator,
Single Isotope Version
Type in molecular formula and this program quickly calculates the
exact mass of a single isotope.
- Online GC and GC/MS Data File Viewer
- reads and display CDF and Agilent .D/data.ms files online.

- Isotope Distribution Calculator and Mass Spec Plotter (2)
[TOOL] Overview This program can calculate the isotopic distribution of a given chemical species. It can also plot either calculated or manually inputted isotopic distributions. This program has been developed by Scientific Instrument Services as part of the Mass Spec Tools Collection. For a complete description of this program visit the Description of this Program Page. This program is still under development. If you have any comments or suggestions we would like to hear from you. Instructions
- Mass Spec Links from SIS (18)
Information, literature and reference sites of interest to the mass spectrometer community.
- SIS on the Web, Report and Statistics
Scientific Instrument Services on the World Wide Web Scientific Instrument Services introduced its WEB site in September 1995. Since that time the usage of the information our our site has continued to grow as more chemists and technicians gain access to the WEB and the resources that are found here. The initial goal of our WEB site was to make information available to our customer base. This includes the Application Notes that we have written on Mass Spectrometers and Thermal Desorption Systems
- Mass Spectrometry (MS) Supplies and Services from SIS (1138)
MS supplies and services including new and repaired filaments, source cleaning, electron multipliers, heaters, temperature controllers, probes, vials, calibration compounds, ceramics, Micro-Mesh® abrasives, cleaning supplies, SIMION®, and NIST (mass spectral library).
- What's New - 1/97 through 12/97
Posted 9/1/97 Chemical Reaction Interface Mass Spectrometry (CRIMS) Scientific Instrument Services is currently developing both GC and LC CRIMS systems. These products are based on the work and methods of Fred Abramson of George Washington University. The GC CRIMS system has been built and is currently being tested in our laboratory. The GC-CRIMS systems will be introduced at the EAS meeting in Sommerset, NJ in November and will available for delivery this fall. Over the next few months we will
