ATC quality extraction

1. Before testing, instruments, flow meters, vacuum gauges, and positive samples should be calibrated to ensure that they are tested within their validity period

2. Each product's corresponding testing chamber needs to undergo 3Q validation before methodological validation can be carried out

3. Testing liquid packaging requires examining the properties of the sample, such as viscosity and vapor pressure, and the vacuum degree during measurement should be less than the vapor pressure of the liquid

4. During the testing process, the parameter setting of time is very important. Appropriate time parameters ensure that the instrument can achieve the ideal vacuum state, while avoiding the gas in the product being completely pumped out during testing

Advantages:

1. High sensitivity mass flow sensor

2. Testing does not damage the packaging, can be reused, and can reduce losses for products with higher costs

3. Can clarify the size of the leak

4. Can be applied to stability investigation and research of products

5. Short testing time

6. The detection limit can reach 1um
