1.4 Malfunction of Instrument
If the instrument doesn’t work according to this instruction manual please send it back to the manufacturer immediately.
2 Introduction
Micro-organisms in the air are a potential risk for contaminating raw materials, semi-finished or end products and processes. Therefore the control of the contamination in the air is very important. The following industries are performing air monitoring as a standard procedure:
∙pharmaceutical industry
∙food industry
∙hospitals
valid from是什么意思
∙cosmetics industry
∙environment
2.1 General Description
According to “The Rules Governing Medicinal Products1” and the International Standard
ISO 14698-1/22, the air must be analyzed for the presence of micro organisms.
The new MAS-100 NT® is a new designed unit for microbiological air monitoring. The microbiological sampling is based on the well known and as standard method established impaction principle3. It works like all other MAS-Systems with standard 90mm Petri dishes or with the adapter for contact plates. The MAS-100 NT® is a further development of the standard MAS-1004 system.
The major advantages are the compact design, the improved security features and the enhanced connection possibilities. The new sampler is very easy to handle. Hard- and software have been developed according to GAMP 45. The total system is fully validated. Improved communication like
RS-232, USB, are available. All functions and parameters as well as the calibration procedure may be done with the new MAS-100 NT® calibration and communication-software. They may also be programmed directly on the unit. A big display on the unit allows the selection of all relevant factors. An alarm- and sample-log records the last 100 events and may be exported or printed at any time. As in other MAS-Systems the mass flow is measured and guarantees a flow of 100 liters/min.
The MAS-100 NT® is validated according to the EN ISO 14698 standard.
2.2 Description of the MAS-100 NT®
The MAS-100 NT® is an improved version of the MAS-100. Improved electronic communication features, validated software, easy and automatic calibration and added safety feature makes this air sampler unique. The impaction speed was also improved and the system is now delivered with a sampling head of 300 x 0.6mm holes. All parameters are controlled and changed from the software or may be programmed directly on the unit.
Note:  The MAS-100 NT® air sampler has been developed according to
GAMP 4. The Soft- and Firmware are validated.
