Search System of SIS Internet PagesA new Search System has been installed into our Internet pages to enable you to easily find parts, products or resource materials on out pages. Our Internet pages have increased to more than 700 pages to date and will expand to 3 or 4 times that amount within the next year. We hope that this search system will prove useful to locate the needed resources. In addition to the Search function we have also added an E-Mail Write us Button on the bottom of each page. We hope that you will write us to give us your feedback, to request additional information or to request price quotes.
New Application NotesThe Following new Application notes are now on line. These articles were presented at the November 1995 Eastern Analytical Symposium.
Eastern Analytical Symposium Poster AwardsOnce again this year competition and awards were presented at the Eastern Analytical Symposium for the best poster presentations in Mass Spectrometry and Gas Chromatography.
The Mass Spectrometry award was sponsored by Scientific Instrument Services and was awarded to Sandy Overton and John Manura of SIS for their presentation on the quality of air inside new automobiles. For this presentation a study was conducted to determine the volatiles present in the air inside new cars. The major volatiles consisted of the siloxanes as well as BHT to name a few. This application note is now on the Internet. Application Note 36.
The Gas Chromatography award was sponsored by J&W Scientific and was awarded to John Manura of Scientific Instrument Services for his presentation on the selection and use of adsorbent resins. This work describes the results of the determination of the breakthrough volumes of more than 200 analytes on 7 different adsorbent resins. The details of this work are presented in the section entitled "Adsorbent Resins."
SIS Mass Spec Filament Repair and Filament Manufacturing Sections
Now Completed on the InternetAs part of our efforts to add our entire product line to our Internet pages, we have just completed the two sections on our Mass Spec Filament Repairs and on our Mass Spec Filament Manufacturing. Accompanying these two sections are articles describing the Facilities at SIS for the Repair and Manufacture of Mass Spec Filaments, our Machine Shop Facilities, our Welding and Brazing Facilities, Quality Control and OEM Manufacturing at SIS. We will continue to add sections to these pages and hope to have the entire Mass Spec Section of our catalog completed by the first of the year.
Short Path Thermal Desorption - Now Completed on the InternetThe section of our home pages relating to the SIS Short Path Thermal Desorption System is now complete. The Short Path Thermal Desorption System mounts directly on top of the GC injection port to permit the direct thermal extraction of volatiles from solid matrix samples or adsorbent resins into the GC injection port for subsequent analysis via the GC or GC/MS. Due to its 'Short Path' of sample flow, this system overcomes the shortcomings of other systems by eliminating long transfer lines and providing for optimum delivery of samples to the GC via the shorted path possible. The technique is highly sensitive and can eliminate the need for solvents in your sample preparation.
Included in this section is a complete description of the Short Path Thermal Desorption System and accessories, Installation directions and application notes relating to thermal desorption.
Also be sure to check out the related Adsorbent Resin Section of our home pages.
Books - Now Completed on the Internet(link outdated) Our section of books available from Scientific Instrument Services is now complete on our home pages. Included in this section are text and reference books on Mass Spectrometry, Gas Chromatography, Liquid Chromatography, General Chemistry, Laboratory Health and Safety, Resume Writting and much more. As new books become available thise pages will be continually updated.
Adsorbent Resins - Now Completed on the InternetAdsorbent resins are used in purge and trap thermal desorption applications as well as for air sampling. SIS has accumulated a vast collection of information of adsorbent resins and it is now available on the Internet. This section contains the accumulation of more than 2 years work to compile the Breakthrough Volume data on more than 200 analytes on 7 different adsorbent resins used in Purge and Trap Thermal Desorption GC. Also included are articles to aid in the selection of adsorbent resins, Backpressure data on the resins and a large number of application notes. This is the most complete collection of information on adsorbent resins ever compiled.
Mass Spec Tips Section - Now Completed on the InternetThe mass spec tips section has just been completed as part of our home page. Most of the entries were previously reported in our newsletter - The Mass Spec Source. If you have additional questions that you would like to ask here or tips that you would like to have included in these pages, please contact us.
Thermal Desorption Application Notes - Now Completed on the InternetSIS has completed the downloading of our Thermal Desorption Application Notes to the Internet. 33 of our application notes relating the thermal desorption, cryo-trapping and headspace GC have been completed. In order to transfer our application notes to the Internet they had to be reformatted with larger graphics. As a result all the figures and charts were redone using color graphics in many cases which makes for a unique and colorful presentation of scientific data.
Next we will begin to download our past newsletters, mass spec tips and also begin to compile the articles from our previous handbooks of service and newsletters relating to mass spectrometers. We will compile and group these articles by subjects such as multipliers, filaments, sources, etc. for easy location and retrieval.
If you have any other suggestions for what should be included here, please let us know.
Repair of Finnigan TSQ-7000 Filaments
SIS can now repair the filaments for the MAT TSQ7000 mass spectrometer. This pin shaped filament requires additional time and materials to repair due to its design and packaging. Therefore the price for the repair of these TSQ7000 filaments is $50.00 each. The part number for this repair is FILREP-7000. Repaired filaments perform as well as new filaments. New filaments are not available from SIS.
Zero Air Generators - Greater Performance at Lower CostThe zero air generator Model 75-83 listed on page C-99 of our catalog has been remodeled. This latest version air generator now produces ultra-zero (<0.1 ppm hydrocarbon content) air at flow rates up to 1000 scc/min. This performance improvement comes at the same time that the price has been decreased to $976.00, a price decrease of over $130.00 . All other performance specification remain the same.

SIS Now a Resource of Information on the InternetSIS Opened their internet home page on the WWW on September 6, 1995. Initially more than 100 pages were downloaded. Major construction will continue for the next 3 or 4 months. Eventually we plan to install our entire mass spec catalog with an index to locate products. The major feature in our home page is called MASS SPEC LINKS. This section is designed to be a reference source of information for the mass spec community. So check it out.

New Kratos Mass Spec PartsA 4 page pamphlet of new parts and accessories for all models of Kratos mass spectrometers is now available. Due to the increased difficulty of getting parts for these instruments since most models have been discontinued, S.I.S. has made a commitment to increase our efforts to supply more parts for these instruments. Call for your free copy of this pamphlet.
New filaments for the Kratos are currently in the design stage and will be available shortly. We are looking for beta test sites to evaluate their performance. If you are interested, give us a call.
S.I.S. Awarded TRP Grant
S.I.S. has recently been awarded a TRP grant to develop air, water and soil sampling inlets for a field portable mass spec for environmental testing. This project is being conducted in conjunction with Teledyne, Monsanto, Phillips and Oakridge National Labs.
