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 be assembling an LC-CRIMS system which will be introduced at Pitt Con in March 1998 and is scheduled for shipment in late Summer 1998. These systems will be available as full GCMS or LCMS Systems based on the new HP 5973 MSD.

The complete line of Wheaton glassware including glass and plastic bottles
is now available online from SIS. Our index system makes it easy to find
your bottle requirements since it classifies bottles by material of construction,
bottle type, and bottle top style. Using our new on line ordering system
makes it easy for you to order your glassware.
Online Ordering: from the SIS Web pages
Available only on Internet Explorer 3.0/4.0
and Netscape 3.0/4.0.
NOT available on Netscape 2.0 but MAY work on other Java Script enabled web browers.

Scientific Instrument Services has begun construction of new shop and
repair facilities at our Ringoes, NJ location. This expansion has been
in the planning stages for more than three years. The new addition more
than doubles our facitities to about 10,000 square feet of offices, shops
and warehouse. The major purpose of this addition is provide us with new
and expanded shop facilities to better serve our customers. Included in
the new expansion are two filament repair rooms, a sandblasting room, a
filament assembly and cleaning room, a welding and brazing room, an equipment
assembly room, a quality control room, a product development room, a drafting
and computer room, offices for our shop and product development staff and
a lunch and lecture room. In addition we are constructing a machine shop
in the basement of the new addition. Construction is expected to be completed
by mid September. This expansion will enable us to expand our staff as
well as add additional equipment and repair capabilities. The old shop
areas in the present building will be remodeled into new offices for our
order to use this on line ordering system.

S.I.S. has developed a new direct probe and probe inlet system for the
Hewlett Packard 5973 MSD. The probe inlet mounts onto the GC/MS transfer
line port and uses an indexed probe introduction guide to permit the direct
insertion and removal of the probe into the MSD source without venting
the MSD or scoring the probe rod. The probe can be either heated ballistically
or at ramp rates in excess of 500 degrees per minute or can be temperature
programmed with up to 25 ramp rate levels. The probe temperatures, ramp
rates, hold times, start and stop are all PC controlled and fully integrated
with the HP ChemStation software. This permits the storage of the probe
analysis parameters in the sample data files and the method files. Shipping
of the new probe inlet sytem is scheduled for Jan 15, 1997.
