13.3.6 Replacing The HSS Nitrogen Canister
Replacement of the Nitrogen Canister is on an as needed basis. When the
pressure is below approximately 140 kPa, the canister will need to be replaced with
a new nitrogen canister. Replacement should be performed between sample runs,
and in a dry and non-hazardous environment, since the front door must be opened.
To change the Nitrogen Carrier Gas canister:
1 Open the front door of the HSS and locate the Nitrogen canister.
2 Press the black release tab on the left side of the Nitrogen canister and the
canister will partially pop out.
3 Remove the canister from the slot. A slight twist may be necessary to remove
can.
4 Remove the plastic protective cap from a new Nitrogen canister and insert into
the canister slot.
5 Press and hold the black release tab while pushing the canister until the
canister stops, then release the tab. The canister should be snug and locked in
place.
WARNING
Do not refill the canisters after use. These canisters are
disposable and not designed for re-filling. Canisters may
fail upon refilling, causing bodily injury.
13.4 Shipping the HSS
The HSS can be readily shipped to a field location. The cardboard box in which the
HSS was received, together with the cut-foam end-caps can be reused. A
reinforced plastic shipping case (IPN 931-406-P1) is also available.
Before shipping the HSS, place an empty vial in one of the wells and insert the
needle in it, for protection. Remove the battery and the canister. Install the
protective caps. No other steps are required to prepare the HSS for shipment.
