Different Helium Leak Detectors

A leak detector is, most of the time, a portable device, programmed to monitor specific conditions. A portable system also offers maximum mobility, which is useful because they are often required to operate within complex infrastructures.

Leak detection process

The helium leak test uses complex equipment as its core that analyzes air samples to provide a quantitative measurement of the helium present in it. The process requires making sure a piece of equipment is working properly and also the experience of an operator. Discover more about package leak detectors by browsing online.

The main test modes are as follows:

Spray Probe – The spray probe method provides maximum sensitivity and the system under test requires connecting the helium leak detector directly. The interior of the system is then evacuated to an acceptable degree before helium is sprayed on the exterior of the system. Any leak in the system allows helium to enter and the leak detector detects it immediately. This allows the source of the leaks to be found precisely.

Tracking Probe – Although this detection procedure provides moderate sensitivity, it is more flexible than the spray probe process. Helium leak detectors require helium to be purged through the interior of the system under test. Helium, seven times lighter than atmospheric air, begins to escape without delay for any leaks that may be present.

Scanning the exterior of the system with a probe will locate the leaks. A process that is far superior to any other traditional method for leak testing (acoustic or bubble emission test or vacuum box test), it is only comparable to some of the specialized techniques such as hooding and bombardment.

How Are Pharmaceutical Packaging Tested?

For manufacturing pharmaceutical products and their launch in the market, packaging plays a major role to ensure that every item reaches end users safely. But, this is not possible until and unless medicines are packed with complete safety measures. 

Certainly, packaging is extremely crucial for the success of any pharmaceutical product and therefore to ensure that the packaging holds the standards required to protect any medicinal items, they undergo several testing phases.

Basically, pharmaceutical packaging testing is done to check the integrity or the leakage and the strength of the seal, and for this, different procedures are followed. Though both are complementary but are completely different processes. But, for the analysis of the pack both testing modes are significant.

For testing the strength of the seal, burst, creep and creep-to-failure testing methods are followed. These methods can be carried out with any material, porous or non-porous. 

Best part is that they can be applied on packs like header bags, pouches, lidded trays, rigid or flexible blisters, and rolled or laminated tubes. As a result, any form of pack can be tested for their strength.

For leak testing, pressure decay is found to be a very effective method to know if there is any leak in flexible packages having non-porous surface material and seals.

There is another method called Closed Chamber Test method. This provides quick and non-destructive testing for blister cards, sealed flexible packages and induction welded bottle seals. In this process, the chamber fixture that encloses the pack pressurizes or in simple words evacuate for a vacuum test. 

Then the machine would stabilize and test for pressures or vacuum decay that later indicates the signs of leakage in the item.
