Find the right starting point

Separate generation, detection and exhaust treatment

This category brings together equipment with three separate jobs: supplying a required gas, monitoring a gas hazard, and treating process exhaust. They do not replace one another. Use the process tool's utility specification and the facility risk assessment to build the equipment list. Hospital medical-gas systems and medical oxygen upgrade kits are outside VVON's scope.

Produce a process gas

Review oxygen or nitrogen generation against the instrument's complete gas specification. Where very low impurity limits apply, confirm that the proposed generator and treatment can meet them.

Compare gas-generation equipment

Monitor an identified hazard

Specify the target gas, detection range, sampling point and alarm interfaces. Honeywell MIDAS S2 is a fixed extractive detector; its cartridge and sampling arrangement must match the application.

All Nanotechnology categories

Before you specify

• Utilities for a nanofabrication laboratory: gases, water, vacuum, power and the safety systems that are not accessories

  Process gases and cabinets, deionised water, vacuum and exhaust, chilled water and standby power, plus the gas detection and abatement that must be commissioned before the first hazardous cylinder reaches site.

• Nanotechnology research infrastructure: the room, the utilities and the instrument set

  Cleanroom class, gases, vacuum, chilled water, vibration and electromagnetic interference decide whether a nano laboratory works. This covers the building side and the instrument classes together, and the order to buy them in.

• Wet bench design for a fabrication laboratory in Bangladesh

  The chemistry list decides the bench, not the other way round. Materials, extraction and duct routes, acid and solvent segregation, spill containment, heated baths, DI water and what has to happen before anything reaches a drain.

• Process gas supply, cabinets and purge panels for a Bangladeshi fab

  Cylinder against bulk, what a gas cabinet is actually for, how a cylinder crossover is done without contaminating the line, and how detection and abatement tie back into the tool that stops when the gas runs out.
