13.1.4 Consumables Required
The following consumables are required for routine analysis when using the HSS.
Compressed Nitrogen — A source of pressurized, high-purity nitrogen is required
for analysis and purging of the system. Nitrogen canisters are available from the
sales agency which provided the HSS, or an external source of nitrogen, regulated
to 700 kPa, may be connected using the 3/16" Swagelok quick connect fitting
located at the back of the instrument.
The nitrogen canisters are available as the following INFICON part numbers:
Box of 6 — IPN 930-432-P6
Box of 12 — IPN 930-432-P12
Box of 24 — IPN 930-432-P24
NOTE: The nitrogen must have less than 50 ppb of volatile organic compounds,
and argon less than 40 PPM. More detailed specifications can be obtained
by contacting INFICON, see Chapter 17, Customer Support.
40 milliliter (mL) Glass Sample Vials — These vials are used for all analyses,
including calibration standards, blanks, quality control samples, and samples
regardless of matrix.
NOTE: The sample vials must have dimensions of 29 mm OD x 81 mm length to
ensure a proper fit in the HSS sample heating block. A proper fit allows the
sample heating block to most effectively heat the samples. Supelco,
Inc.(800 247-6628) offers clear glass vials of this size with PTFE-silicone
septa and open-top phenolic closures. The vials are Supelco part number
2-7180 (box of 100).
Water — Water is used for syringe cleaning, blank analysis, calibration standard
preparation, calibration check standard preparation, as well as sample dilutions if
necessary. This water must be free from volatile organic compounds, or
"VOC-free".
Calibration Mix — This mix should consist of the target compounds for sample
quantitation. The mix is used to prepare standards for a calibration curve. The
calibration curve is used for quantification.
INFICON has created a 4 component mix used as Internal Standards for
Headspace Sampling (HS) runs. This mix is added in conjunction with calibration
mixes used to write calibration curves for quantification methods. The part number
for this mix is:
4 component (HS) Internal Standard — IPN 071-748
NOTE: Calibration Mixes may be purchased from a variety of laboratory supply
businesses in liquid form, usually in a methanol matrix. Typical laboratory
mixes are readily available as off-the-shelf items, while custom mixtures
can be made to specifications.
