Your ion gauge says the pressure is fine, but it cannot tell you what is actually inside the chamber. Here is how a residual gas analyzer separates your residual gases by mass, why every reading is really a calibrated ion current, and when an RGA beats (or joins) an ion gauge on your system.

Where does your leak detector's number actually come from? It traces back to a calibrated leak, the small reference device that makes a leak rate measurable. In this article we break down how permeation and capillary calibrated leaks are built, how internal and external calibration differ, and how to keep your standards accurate and traceable over time.

How do you actually measure a vacuum? There is no single sensor that reads honestly from one atmosphere to ultra-high vacuum, so every system pairs gauges with overlapping ranges. In this write up, we break down how Pirani, thermocouple, capacitance manometer, and ionization vacuum gauges work, why readings shift with gas type, and how to choose the right measurement package for your chamber.

Why do moisture-sensitive components still fail after reflow? Often it is what happened in storage, not on the line. Learn how airtight acrylic desiccator cabinets keep humidity out with O-ring seals, cam clamps, dry gas ports, and digital hygrometers, how MSL floor life works, and when dry storage beats a vacuum chamber.

Bubble tank too blind and decay test too blunt for your tightest spec? Helium tracer gas testing with a mass spectrometer leak detector pushes sensitivity down to roughly 1 x 10-12 mbar l/s. Learn why helium is the tracer of choice, and when to run vacuum integral, sniff, or accumulation methods on your parts.

Your helium leak test came back clean, but the chamber still won't reach ultimate vacuum? The culprit is probably a virtual leak, and in this article we explain how trapped gas pockets masquerade as real leaks, how to confirm one by watching for pressure bursts and thermal sensitivity, and the design tricks, from relief holes to vented fasteners, that eliminate them for good.

Every leak test on the planet leaks a little. The question is never whether your specimen will hold a perfect seal, it is whether the leak is inside the tolerance your process demands. When a pressure decay or vacuum decay test fails, the failure usually comes from one of two places: a real breach in the part, or an error in the way the test was set up and run. The curve itself tells you which one you have, if you know how to read it.

Bubble testing is a simple yet powerful technique for detecting leaks in sealed systems and components. Also known as bubble leak testing or the bubble emission test, this method relies on visual clues, the formation of bubbles, to reveal any unwanted openings in a product. It’s a time-honored approach used across a variety of industries to check everything from spacecraft components to food packaging for integrity.

Ever wonder how aerospace instruments or satellite components are tested for the low pressures at high altitudes? Or how automakers ensure a car engine will run smoothly on a mountain pass? The answer lies in altitude simulation chambers, specialized vacuum chambers systems that mimic the low-pressure conditions of high altitudes. By pumping out air to create lower pressure inside a sealed chamber, these devices can reproduce the environment found thousands of feet above sea level. This technology allows engineers and scientists to accurately simulate any altitude in their laboratory.

Find out how degassing really works and the science and applications of degassing chambers and systems. See how vacuum degassing enhances product integrity, removes trapped gases, and improves material quality across industries like resin casting, metallurgy, aerospace, and food processing.

In the rapidly evolving industries of food, pharmaceuticals, and medical device manufacturing, maintaining package integrity is not just a regulatory requirement, it's a commitment to consumer safety, product efficacy, and brand reliability.

ASTM Packaging Standards Comprehensive Series (Part 1 of 8). Packaging holds a pivotal role in safeguarding products across multiple industries, from preserving the freshness of food to maintaining the sterility of medical devices. To uphold consistent performance and secure safety benchmarks, many organizations rely on the comprehensive standards offered by ASTM International.

ASTM Packaging Standards Comprehensive Series (Part 2 of 8). Ensuring the integrity of package seals and container closures is paramount for protecting contents from contamination, leakage, or spoilage. A failure in seal integrity can compromise sterility for medical products or lead to food spoilage and safety hazards.

Packaging not only needs to be properly sealed; it must also survive the rigors of shipping and handling. Boxes get dropped, pallets get vibrated on truck beds, and air pressure or temperature can fluctuate in transit.

The food industry needs packaging that preserves product freshness, prevents contamination, and withstands the journey from production line to pantry. Food packages come in many forms including, but not limited to metal cans, glass jars, plastic bottles, flexible pouches, cartons.

The biotech and pharma sector deals with products that are often high value, highly sensitive, and sometimes hazardous. Vaccines, drugs, lab reagents, or diagnostic samples must be kept within strict temperature ranges, and protected from contamination.

Medical device packaging often has to maintain a sterile barrier from the point of sterilization until the moment of use in a hospital or clinic. The packaging, commonly a pouch, tray with a lid, or a blister pack, must withstand sterilization processes, like ethylene oxide gas, gamma irradiation, or steam, without degradation, and then protect the device during shipping and storage.

The aerospace industry deals with packaging for components ranging from delicate electronic avionics to large, heavy structures. Often, these items are high-cost and mission-critical, so any damage in transit can have significant consequences.

We have worked with thousands of packagers across various industries such as food, medical, biotech, pharma, automotive, aerospace, etc. and we have learned that the most successful packagers use a highly iterative, open minded, and systems thinking approach.

Simulating the Martian environment on Earth requires reproducing Mars’s thin, cold, CO2-rich atmosphere inside a controlled chamber. This enables testing of equipment, chemical processes, and even biological organisms under realistic Mars conditions.

Leak and Quality testing has never been more critical. Many industries such as automotive, aerospace, medical device, consumer electronics, food, R&D, and general manufacturing depend on precise, reliable leak testing methodologies to ensure seal integrity, product quality, and customer safety.
