2.2 Piping
IMPORTANT
•
Do not remove the blind plugs at the analyzer piping connections until starting piping work to
prevent deterioration of the columns. On the condition that carrier gas is not supplied even
after the blind plugs are taken out or while the analyzer is out of operation, the column has
the risk of deterioration. In these condition, fix the the blind plugs at each vent with carrier
gas enclosed.
• Use an anti-corrosion material for the pipes and pipe fittings.
•
Never use pipes with too large a diameter for the sample inlet piping to reduce the dead
time. However, use a little larger pipe for the exhaust line so as not to apply back pressure to
the venting lines.
• Use pipes and pipe fittings free from interior contamination such as grease, oil or other
substances. The contamination damage the analyzer. Before connecting the pipes,
completely air-purge their interiors.
•
Carefully connect the pipes so that there is no leakage from the pipe connections such as
the joints.
• Use filters or other appropriate pipe fittings to prevent dust, moisture, or other foreign matter
from getting into the analyzer.
2.2.1
Types of Piping and Installation
The types of piping are shown below.
Note that the types of piping and quantities of individual pipes required vary with the
specifications such as the analyzer type and detector type (TCD, FID, or FPD).
See the flow sheets in the “Operation Data” for implementing piping.
Control unit
(A) Air output for stream valve 1 to 8 (AIR OUT 1 to AIR OUT 8)
Isothermal oven, large isothermal oven, programmed temperature oven
(B) Protective gas (instrumental air) inlet (PURGE AIR)
(C) Inlet/outlet of sample gas (SAMPLE 1 IN, SAMPLE 2 IN, SAMPLE 1 OUT, SAMPLE 2 OUT)
(D) Carrier gas (CARRIER 1, CARRIER 2)
(E) Hydrogen gas for combustion (H2)
(F) Make-up gas (MAKE UP)
(G) Air for combustion (BURNER AIR)
(H) Air output (ATM 1, ATM 2)
(J) FID vent (FID 1, FID 2)
(K) FPD vent (FPD 1)
(L) TCD vent (TCD1, REF.1, TCD2, REF.2)
(M) Vent (VENT 1 to VENT 10)
Analyzer base sampling system (GCSMP)
(1) Sample inlet (STREAM #1 to STREAM #12)
(2) Standard-gas inlet (STANDARD #1 to STANDARD #3)
(3) Sample bypass vent (STREAM #1 B/P VENT to STREAM #12 B/P VENT)
(4) Sample vent (SAMPLE VENT 1 to SAMPLE VENT 3)
