DE-RQ26-08NT00520 the U.S. Department of Energy, National Energy Technology
Laboratory (NETL), Pittsburgh, PA intends to purchase the following:
Gas Chromatograph (GC), with Programmable Pheumatic Control (PPC); Mass
Spectrometer (MS), with Electron and Chemical Ionization; Headspace
Sampler;
Controller; NIST 2005 Compound Library; Laser Printer; Monitor and
Installation
as per the specifications listed below:
Detailed Specifications for Requisition number 08NT005419
Gas Chromatograph (GC), with Programmable Pneumatic Control (PPC). 120 Volt
20
amp oven, GC and auto sampler are fully controlled from the instrument
keyboard, single capillary-column injector with (PPC), Ethernet port to
connect
GC to PC via a local area network (LAN) which provides a digital to digital
connection between GC and PC.
a. The GC Oven should be a twin-walled oven with concentric air intake to
save
time between chromatographic runs. The gas chromatograph oven must be
capable
of fast cool-down from 450 oC to 50 oC in less than 2.0 minutes.
b. The gas chromatograph oven should have the capability to allow the user
to
limit the cooling rate to prevent ghost peaks caused by column-bleed
chilling
and carrier-gas contraction.
c. The gas chromatograph must have the ability for an Autosampler pre-rinse
to
perform a time-consuming syringe rinse with sample before the gas
chromatograph
is ready. This will reduce time between injections.
d. The gas chromatograph must have a color graphical touch-screen interface
e. GC must have prevent technology all supported from same manufacture.
This
is used on existing GC for Fuel Dilution analysis. These are the prevent
modes
of operation:
Time-Saver mode prevents higher boiling components or residue from
entering a
column. This is currently being used in Laboratory for Fuel Dilution
analyses.
Enhanced Solvent Purge mode isolates the column and detector from the
effects
of high levels of solvent. Eliminate solvent flooding of the column or
allow
the use of solvents such as Methylene Chloride with an ECD.
Isolation Mode allows a septum change without interrupting carrier flow.
Perform maintenance on the inlet while chromatography is taking place.
f. Mass Spectrometer, MS-Vent mode allowing column replacement without
cooling
and venting the MS, the ability to use any column and flow rate for GC/MS
and
to split the column effluent to a second detector.
g. The temperature programmable injector must be able to be operated in the
split, splitless or on-column mode of operation. This is consistent with
current GC in the laboratory.
h. The temperature programmable injector must be able to be heated at a
program
rate that is a constant 5 C above the column oven temperature program. It
must also be able to be programmed independently using an independent
heating
program with 3 plateaus and two ramps.
i. The Temperature Programmable Injector must operate between 50 oC to 500

or
50.0 L (with a 50L syringe).
n. The Autosampler must have 4 wash and 4 waste vials.
o. The operator must be able to access the injection ports of the gas
chromatograph for septum changing, etc., without removing the Autosampler.
p. The Autosampler syringe must not be left standing over a heated
injection
port when not in use.

mass spectrometer must be able to be set up to 12,500 Da/sec.
c. The mass spectrometer must use a long life sealed Photomultiplier
Detector
and not an Electron Multiplier which is an expensive consumable item.

Assembly to minimize contamination and to focus the ions down quadrupole
assembly.
e. The quadrupole must be made of molybdenum and be cleanable in the field.
