The heart of the most sensitive and accurate instrument for detecting extremely small leaks is the mass spectrometer, which is used to measure the rate of flow of a tracer gas through leaks using vacuum, pressure or vacuum-pressure techniques. The mass spectrometer detects the tracer gas and converts it to an electrical signal proportional to the size of the leak. Helium is usually used as a tracer gas because of its unique combination of properties:
Helium is extremely rare in the atmosphere, so there is little ambient “noise” to interfere with leak measurement
Non-explosive, non-toxic, completely inert (no contamination of the tested product)
Will not contaminate and desensitize its own detector as is common with detectors using other tracers
Helium is a small, light molecule (mass 4) and will flow readily through extremely small leaks

A standardized solution for thermal leak testing equipment. Specifically designed for thermal leak detection applications. The Scepter is complete and in stock. We offer this concept for fast delivery of a custom system. The Scepter upon customer order would require custom tooling which is placed inside the chamber(s) to complete the system. The Scepter is offered as a single, dual or IHX configuration.
Custom solutions for medical product leak testing equipment. Methods of leak detection used by medical device manufacturers are evolving to meet increasingly stringent quality standards. Testing for leak integrity is critical in the device industry because product failure presents significant hazards to patients and healthcare professionals and liabilities for manufacturers.
Solutions for automotive fuel delivery leak testing equipment. Leak testing requirements for fuel system components have been lenient (0-2 cc/sec). Amendments to the EPA Clean Air Act and the California Air Resources Board have imposed evaporative vehicle emission standards resulting in a more stringent leak test requirement. To fulfill these test requirements, VIC has developed ultra-sensitive mass spectrometer methods to leak test fuel system components, including fuel tanks, tube and flange and fuel rail assemblies.
Solutions for automotive fuel rails leak testing equipment. Fuel rails need to be tested for leaks during component production at a supplier level to prevent leakage in the engine compartment. High-pressure, direct-injection fuel rails have a maximum allowable leak rate spec of 10-4 atmospheric cubic centimeters per second (Atm-cc/sec). Leak testing fuel rails with tracer gas, often with the fuel injectors installed, in a vacuum chamber is a common process.
The MD-490S is a leader among portable tracer gas leak detectors. With a response time less than 0.5 seconds, sensitivity to 10-8 direct reading atm-cc/sec, and the ability to zero-out background, this is the most aggressive portable leak detector in the industry. The MD-490S is fully integrateable with our SmartChargeIII Evacuation and Backfill Station.
MD-490S Dual Gas is the most advanced sniffing Helium/Hydrogen leak detector designed specifically for industrial environments. The MD-490S Dual Gas utilizes VIC’s own industrial-grade mass spectrometer to achieve the highest sensitivity, fastest response-time, and smallest footprint. With a touch of a button, this dual gas unit can detect either Helium or Hydrogen tracer gases, while using a single built-in dual purpose calibrated gas leak.

Introducing a solution to lower the cost associated with tracer gas consumption While industries strive to meet increasing demands to offer higher quality products at lower prices, the need to efficiently recycle process gas becomes apparent. Helium Recovery features a group of high efficiency gas recycling systems that significantly reduce tracer operating costs. The Helium Recovery Systems offered consists of ASME coded pressure tanks, a set of compressor(s), gas analyzer, microprocessor controls and all necessary valving, gas regulation and piping.
A fully automatic, custom configurable evacuation and gas backfill system with built-in gross leak test that may be used to pre-charge products under test with gas for leak detection or for any gas charging application that requires evacuation and subsequent pressurization of a test product.
Gas booster systems produce high-pressure process gas supplies from lower pressure sources, typically boosting a shop air source. Base units provide up to 600 psig pressure output. Options include higher pressure outputs and process gas drying capabilities. Can be configured for single gas or dual gas boosting.
The OM Series gas calibrator leaks utilize a precision tapered glass capillary as the leak element. Gases pass through a single orifice, with the leak rate dependent upon size and gas pressure. To prevent clogging of the fine orifice, a unique particle trap is located between the capillary tube and outlet fitting.
