Preface Hydrogen Safety Precautions Using Hydrogen with ISQ To use hydrogen with the ISQ, you must always shut off the GC carrier gas before venting or turning off the ISQ. There are three screws on the ISQ that must be in place. These are already attached to your instrument when you purchase it. Figure 1. Hydrogen Screws on the ISQ Left Top Cover Screw Right Top Cover Screw Front Panel Screw Make sure all the covers and panels of the ISQ are firmly attached before powering on the ISQ. If you vented the system, make sure the vent valve is tightly closed before powering on the system. Make sure the vacuum manifold is vacuum-tight before powering on the system. Note When powering on the system, do NOT reach over the top of the instrument to power it on. Instead, reach around the right side or go to the back of the instrument and flip up the power switch. xiv ISQ User Guide Thermo Scientific
Hydrogen Connection Guidelines Use the following guidelines to safely connect hydrogen to your system: Preface Hydrogen Safety Precautions • Piping—Hydrogen must be delivered to equipment using appropriate piping and be done in such a way as to pose essentially no hazard to end-users. Piping systems for the delivery of hydrogen should be designed and installed by a person qualified by specific training and experience with hydrogen piping systems. Stainless steel is usually recommended because it is a safe, cost-effective material. Piping of black iron or copper must not be used, as the pipe can become brittle with age. Elastomeric/plastic tubing of various plastics and polymers should not be used, unless the tubing is approved for use with hydrogen. If elastomeric/plastic tubing is used for hydrogen gas delivery, the tubing should be tested for hydrogen permeability to minimize leakage. The hydrogen piping system must be flexible enough to endure routine thermal expansion and contraction. The system should also include considerations for the most severe condition of temperature and pressure expected during service. Piping and supports must be able to withstand static loading introduced by such things as ice and snow; and dynamic loading from high wind and earthquake. Caution should be used if burying hydrogen piping. Proper controls should be used to protect against damage and corrosion, and also to prevent Hydrogen from entering a building if there is any leakage. • Fittings—All fittings must be of the proper type approved or designed for use with hydrogen gas. Use as few fittings as possible to minimize the potential for leaks. After installation, ensure that leak testing is carried out prior to system use, and on a regular basis. There must be no PTFE tape or other things like plumber's putty used to enhance a seal, as this actually is a detriment to a good seal. Ideally the best installation would use stainless steel tubing with appropriate gas-tight fittings. Welding is usually preferred for joints in hydrogen piping systems since welding provides a better connection and reduces the potential for leaks compared to mechanical fittings. Soft solder joints are not permitted for hydrogen systems (due to the low melting point of soft solder and its potential for brittle failure at cryogenic temperatures). Brazed joints are permitted, but such joints should be protected against the possibility of external fire. Tubing connections should be clamped to barbed or press-fit type connections. Hose clamps or jubilee clamps must not be used. • Valves—All valves must be suitable for hydrogen service and for the specific operating conditions. Valves, including regulators, must not be used for hydrogen, unless they are designed and identified for such a use. Ball valves are often chosen because of their superior leak tightness through the valve seat. Pneumatic operators are usually chosen for remotely operated valves so that potential ignition sources (electricity) are remote from the valve. Thermo Scientific ISQ User Guide xv
