SIS Continues to Expand its Facilities to Serve the Scientific Market

SIS is continuing to expand our facilities and staff to better serve the needs of the scientific community. In the past 6 months we have added a total of 5 new technical people to our shop facilities. This is a 25% increase in staff which brings our total staff size to 25 people.

SIS has made major efforts in the past year to expand our machine shop. We have added a new computer controlled 4 axis vertical machining center (CNC Mill) and a multi-axis Mori Seiki turning center (CNC Lathe) to the machine shop. We now have a staff of 3 full time machinists in the machine shop to operate this equipment. This new equipment permits us to machine parts and components for end users, OEM's as well as our own parts for the thermal desorption systems and probes we develop and market.

Our manufacturing begins with 3-dimensional Computer Aided Design (CAD) of parts and assemblies using CadKey software on a PC. These drawings are then downloaded to another PC with Computer Aided Machining software (CAM). The CAM software converts the CAD drawing into the CAM format which can then generate the tools and machining tool paths for the machining of the part on the CNC equipment.
Next the tool paths and tool selection generated by the CAM software is downloaded to the CNC equipment for machining of the components. The correct tooling is automatically loaded by the automated tool loaders into the CNC machine. The feed and cutting speeds for the selected tools are determined by the software depending on the materials being machined and the part is machined to the required specifications with tolerances better than 0.002". Complex parts can be machined due to the 4 axis capabilities of the equipment.
After the parts are manufactured they are cleaned in our new Crest Closed Loop Ultrasonic Cleaning system. This system uses no organic solvents, only water, for the cleaning process. The water is continually recycled through ion exchange resins and carbon filters to maintain its high purity. The parts to be cleaned are immersed in the high purity water at elevated temperature and ultrasonics are used to super clean the parts until; they are; totally free of any contamination.
The result is a high precision manufactured part at reasonable cost.

A number of brochures describing out machine and repair shop facilities and capabilities can be downloaded from our web site.

SIS Obtaining ISO Certification

SIS is in the process of obtaining ISO Certification. ISO is an international program to provide for quality and improved customer service in an organization. It is comparable to GLP in a laboratory. Companies that are certified must document all their procedures and processes, provide for inspection and high quality control for their products and strive for continued quality improvement and customer satisfaction.

We made a decision to pursue ISO Certification about a year ago in order to improve our quality control procedures, to improve customer service, to better document what we do and the way we do it, and to position the company to better serve the needs of the scientific community. We started the ISO Certification process about 3 months ago and are well underway in the process. We hope to achieve final certification in December of this year. We anticipate that you will see the impact of the changes that will occur as a result of this program.

SIS AutoProbe™  introduced at PittCon 2001

SIS introduced the AutoProbe™ - an automated direct probe for the Thermo Finnigan TRACE™ mass spectrometer at this year's PittCon meeting in New Orleans.

The AutoProbe System is an Automated Direct Exposure Probe (DEP) for the Finnigan TRACE Mass Spectrometer System with a dual EI/CI source. The AutoProbe System injects samples directly into the MS source for mass spec sample analysis with no chromatographic separation. This permits samples to be analyzed in 3 minutes or less. The AutoProbe operates in the Thermo Finnigan Xcalibur™ MS Software environment and is fully integrated with the Xcalibur software, including system setup, methods setup, system operation and data storage.

Applications of the direct probe technique include the screening of drug and pharmaceutical samples, quality control sample analysis, spot analysis of chemical reaction mixtures to monitor rates of synthesis, and the analysis of compounds which cannot be chromatographed. The AutoProbe System is used where high volumes of samples need to be analyzed quickly or it can be used in an "Open Access" environment where it can be operated by multiple users with minimal MS expertise.

Additional Details on the AutoProbe are available on our WEB site in the following files.

Vacuum Pump Exhaust Filter System from SIS

SIS has recently introduced vacuum pump filter kits for the rough pumps on your MS systems. These systems are recommended for areas where it is not possible or practical to exhaust the MS vacuum pumps outside the building. The filter system consists of two layered filters. The first filter is an oil mist eliminator, which captures the heavy hydrocarbons from the vacuum pump exhaust and returns these oils back into the pump. The second stage of filtering, consists of a disposable charcoal trap, which traps the more volatile organic compounds which are exhausted from the vacuum pump. Four different Exhaust Filter Kits are now available for a large selection of vacuum pumps.

We have complete Exhaust Filter Kits for specific models of vacuum pumps. Each kit includes a Koby Charcoal Trap, an Oil Mist Eliminator and all the fittings, centering rings, and clamps needed to complete the assembly of the filter system to the vacuum pumps. For additional details on the kit contents, descriptions and pictures, click onto the Kit # to link to the appropriate WEB page.

Two Stage Filter Kits for most Vacuum Pumps are available from SIS.

We have three application notes on our web site with scientific studies demonstrating the effectiveness of these vacuum pump exhaust filters.

A four page flyer on vacuum pump filters can also be downloaded from our web site (478 K).

SIMION 3D version 7.0 Ion and Electron Optics Program

SIMION 3D version 7.0 is a PC based ion optics simulation program designed for instrument design of mass spectrometers and other ion optic instruments. At SIS we use this program to design new mass Spectrometer filaments and to study mass spec source design. Manufacturers of electron multipliers use this software to design their detectors and instrument designers use it to design new instruments and to maximize the sensitivity of the instruments. Use this powerful software to study ion source and detector optics in time-of-flight, quadrupole, ion trap and magnetic sector mass spectrometers in order to discover improvements that can be made to your instruments as well as to develop new instrument designs.
