The particular attention paid to leak tightness of pharmaceutical containers has been increasing within the past months. Seidenader stays abreast of these changes with the development of a module for Head Space Analysis (HSA). Besides the penetration of oxygen and its possible reaction with the product, the loss of sterility of parenteral products is the most serious threat to the health of patients. Up to 600 vials per minute and 100 measurements per container are analyzed using the Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology.

The vials pass the laser head in a precise handling system. The laser beam, tuned over a certain wavelength range, is sent through the headspace of the vial. A photo sensor receives the transmitted light and determines the absorption profile of the headspace gas. The analysis of this profile results in precise information. The obtained data are compared to threshold values to generate pass/fail decisions.

The  Seidenader  HSA module can be integrated into Seidenader automatic inspection machines as a complementary check to camera inspection, as well as it may be integrated onto Seidenader's 1C platform as a stand-alone HAS inspection machine.
