— 28 SPECTRO ARCOS FHX3X — 08.02.2022
5.7.1 Argon
Information! Measurement errors!
Impurities in the argon supply will produce measurement errors and/or will
make ICP operation impossible.
Ensure oil and grease-free installation of the argon supply line.
An argon supply system is required for the instrument.
A suitable pressure reducer is required for the argon supply system (bottles or
liquid gas tank).
Adjustable output pressure 0 to 10 bar
It is imperative not to exceed a maximum argon inlet pressure of 8 bar
(116 psi).
The tubing for the argon supply system is included in SPECTRO’s scope of supply
(5 m long, OD/ID = 8/6 mm). This tubing is screwed to the connection point on the
right-hand side of the instrument. The connection point to the instrument is
included in the scope of supply. The connector on-site is customer-specific and,
therefore, not part of the delivery.
The following flow quantities are used for aqueous samples during normal
operation:
Coolant: 9 to 20 l/min, typically 12 l/min
Auxiliary gas: 0.6 to 3 l/min, typically 0.8 l/min
Nebulizer gas: 0.4 to 1.5 l/min, typically 0.8 l/min
5.7.2 Oxygen (optional)
Inlet pressure during
operation
4.0 bar (58 psi)
Quality ≥ 4.5 (99.995 %)
Flow rate The flow rate depends on the application.
