Particle Filters maximize life of leak detectors and pumps.July 10, 2006 -
MaxP(TM) particle filters are designed to enhance reliability, useful life, and mean time between maintenance of mass spectrometer helium leak detectors (MSLD) and associated vacuum pumps. Reusable stainless steel filters are installed by replacing centering ring in inlet port. Models are available for most MSLD systems, including Alcatel, Balzer, Dupont, Edwards, Leybold, Varian, Veeco, and VIC systems.

New HLT Filters Eliminate Contaminants, Maximizing Performance of Vacuum Systems and Mass Spectrometer Helium Leak Detectors
Helium Leak Testing, Inc. (HLT), a national provider of helium leak detection systems and services announced its new line of MaxP(TM) particle filters for Alcatel, Balzer, Dupont, Edwards, Leybold, Varian, Veeco, and VIC systems. The filters are specifically designed to improve the reliability, useful life, and increase the mean time between maintenance (MTBM) of the mass spectrometer helium leak detectors (MSLD) and associated vacuum pumps. Models are available for most MSLD systems. The cost-saving MaxP filters can be viewed at www.heliumleaktesting.com and available directly from HLT.
Based on nearly 30 years of experience, HLT has discovered that particle contamination of the pump oil in MSLDs creates excess downtime in leak testing. These filters minimize this operational inefficiency, while minimally affecting pumping speed when the MaxP filters are installed and clean. In addition, measurement accuracies are maintained, as helium retention is practically nonexistent with clean filters. The reusable stainless steel filters are easily installed by replacing the centering ring in the inlet port.
More on HLT's MaxP Filters
An MSLD is comprised of a very complex analytical collector that separates the residual gases in the vacuum cavity. As an end result, the only gas that finally reaches the intended collector is helium, which is transmitted as the leak rate. With clean, ideal surroundings and clean parts, an MSLD can operate at maximum performance for many years. However, conditions are typically not ideal. Contamination is always present and often damages the integrity of the MSLD's vacuum and analytical components.
Detrimental contamination is everywhere, unless the leak detector is operated in a super cleanroom. The atmosphere introduced where the chamber is open contains fibers, dust, hair, skin scale and other debris. The parts under test may also carry these same contaminates plus particles from the manufacturing and assembly. Chips from machining slag from welding, solvents from cleaning, and particles from other processes contribute to leak detector contamination.
Vacuum pumps are different in that it is their job function to remove the contamination along with the air from the chamber and/or parts being processed. However, the useful life of the pump can be increased tremendously by minimizing unnecessary contamination as much as possible.
HLT's MaxP filters capture most of the debris, that harms both the leak detector and vacuum pump systems. These filters minimize the loss of performance from leak detectors and pumps, while extending the system life.
About Helium Leak Testing, Inc.
Founded in 1960, Helium Leak Testing, HLT, provides equipment sales and services nationally to multiple industries that require leak detection, test fixtures, production testing, leak standards, vacuum gauge calibration, vacuum pump maintenance. The company designs, builds and installs commercial and custom leak detection systems for applications in aerospace, automotive, oil, medical, food, semiconductors and power generation markets. HLT's Production Test Division provides outsourced testing and packaging of parts and components for OEMs in many of these same industries. The customized automated leak detector systems increase throughput and result in significant cost savings. The Services Division develops and implements solutions to industrial problems such as leaks, inadequate test fixture design, non-calibrated leak standards and vacuum gauges, inefficient vacuum pumping rates, all of which can cause production inefficiencies and potential measurement errors. The Services Division also develops procedures and trains production personnel in leak testing methods and techniques.
