JMC (Japan Machinery Company)

For Completely Non-Destructive and Rapid Container Closure Integrity Test

Oxygen concentration, pressure, moisture content inside the transparent container such as vials and ampoules can be completely Non-Destructive measured in just a few seconds. Conformity to container integrity test USP 40 NF 35 (USP 1207.2 2.2: Laser-Based Gas headspace Analysis).

- A test results not meeting specification could not be due to package leakage, or could result from improper package filling or assembly processes that caused the package headspace to be out of specification.

- A test result that meets specification may confirm package integrity if enough time has elapsed since product–package preparation for measurable leakage to have occurred, assuming that the initial preparation of the test sample met manufacturing standards.


- Change in pressure /oxygen concentration is measured with the lapse of time.

- There could be leakage from the container. Problems in the filling/assembly stages could be found.


- Change in pressure /oxygen concentration with the lapse of time is within the tolerance.

- No leakage from the container. There is no problem in the filling /assembly stages. By using a decompression chamber, products plugged under atmospheric pressure also can be measured.


Nitrogen Substitution Rate Confirmation

- The measured oxygen concentration can be referred to for optimization of the nitrogen filling.
- Can check validated nitrogen substitution amount.

What can the inappropriate substitution rate tell us?

- Nitrogen gas substitution power can be insufficient.

- The rubber cap can be not properly plugged, etc.

Quality Assurance and Hot/Cold Spot Confirmation for Lyophilized Formulations

- Predicts the degree of dryness of a lyophilized formulation from the moisture content in the headspace.

- Mapping of moisture level of the lyophilized formulation chamber.


Compliant with “Laser Gas Headspace Analysis Method” listed in USP <1207.2>

Highest Detection Limit

Typical measurement accuracy (actual values)

SD when measuring the φ30mm transparent vial with 20% oxygen inside.

- Approx. ±0.1 when measurement time/vial is 10 sec.

- Approx. ±0.15 when measurement time/vial is 5 sec.

*Measurement accuracy depends on the size, thickness accuracy, transparency, color, etc., of the container.
