Air Sampling Devices articles

Sometimes the smallest things can be one of the biggest headaches!

During the Apollo missions of 1969 to 72, the tiny particles of lunar dust turned out to be a major issue.

Curious Droid, a video blogger, Paul Shillito has created a y-tube video explaining the hazard that moon dust (mostly silica) affects health of astronauts and machines. Even though it was published in 2017, it is a very informative treatise on an out of this world subject.

Welcome back to the continuation on the “Hard To Find Filters”. Part 2

In the last post I covered the first 2 points of the ideal filer.

In this post I will detail points 3, 4 and 5

Point 3 … be pure, down to nanograms, of the substance that you are measuring.

Ideally, the filter used to capture particles in air or liquid for analysis, should contain zero of the substance you are sampling for. In this manner

Announcing New Hard to Find Filters
Filters have been the go-to method for sampling air in determining particulate contamination.
Before I get into the “hard to find” filters, let us talk about filtration.

The ideal filter should:

1. be able to capture “everything” down to the nanometer;
2. never plug;
3. be free of the substance that you are measuring, down to nanograms;
4. contribute zero pressure dr
