Product Q&A
Q:What specialty gases do you supply?
A:
We provide custom calibration gas, standard reference gas, shielding gas, zero gas, and mixed specialty gases. Components include methane, helium, argon, nitrogen, oxygen, hydrogen, carbon monoxide, etc. Gas concentration can be customized according to customer requirements.
Q:Can gas concentration be customized?
A:
Yes. We prepare gas mixtures based on customers' target concentration, uncertainty tolerance and application scenarios (semiconductor, environmental monitoring, welding, laboratory analysis). A gas certificate will be provided with each cylinder.
Q:What cylinder sizes are available?
A:
Common options: 2L, 4L, 8L, 10L, 40L steel / aluminum cylinders. Cylinder pressure can be 10MPa / 15MPa / 20MPa as requested.
Q:Do you supply new cylinders or refill only?
A:
We support two modes: Sell brand-new cylinders filled with gas; Refill service for customer-owned qualified cylinders (only valid inspected cylinders accepted).
Q:What valve types can you fit?
A:
We offer CGA, DIN, BS, ISO standard valves, also optional stainless steel diaphragm valves for high-purity & trace gas applications.
