Description

General description

The portable and battery-operated MAS-100 Atmos^® is designed for failure-safe and accurate sampling of pre-selectable compressed gases.
Like all MAS-100^® microbial air samplers, the equipment principle is based on sieve impaction. The impaction of microorganisms takes place under pressure to prevent any harm to microorganisms caused by fast dynamic decompression.
A specific amount of compressed gas gets aspirated through a perforated lid (300*0.6mm) which captures the available microbes onto the surface of an agar plate (90-100mm pertridish) with an impaction speed of 19.7m/s.
The state-of-art design provides a nominal d50 value of 1.1 μm at a default flow rate of 100 liter/min (LPM).
An optional perforated lid with 300x0.47mm holes can be used for pre-selected flow rates of 50 LPM to achieve the same d50.
The system measures the current pressure, indicated either in bar abs. or Psi (1.2 to 7 bar abs. = 17.4 to 101.5 Psi), and regulates the flow rate based on a mass-flow sensor for each pre-selected gas type to 100 LPM. In case of low flow provided by the gas pipe, the instrument can automatically switch to 50 LPM. The decompression after sampling is performed automatically.

Data Integrity:
The MAS-100 Atmos^® offers various operation modes for different workflow scenarios configurable via browser-based user interface:

• Freely accessible configuration by any operator (out of the box)
• 21 CFR Part 11 compliant management.
• Manage connected bar code reader.
• 2 D bar code including all sample data supports wireless transfer into EM software systems

A full audit trail including e-signatures as well as sample reports and error logs are available for download.
Individual configurable hardware keys combined with a PIN code allow 21 CFR Part 11 compliant login including defined access rights the selected user role as well as traceability.
The touch screen is used for operation and to display important information, such as current pressure (units selectable in bar abs. or Psi), battery status, date and time, sampling status and result data as a 2D bar code. A graphical user guide can be selected for easy instructions of workflow steps.
The MAS-100 Atmos^® is powered by a Lithium-ion rechargeable battery that assures long battery life without routine discharging.

Other Notes

Operation of the pump is easy, and the following steps can be followed:
1.Insert the appropriate agar plate and select sample parameter (gas type, volume)
2.Connect the instrument to the gas outlet (PTFE pressure connection tube is provided with a 3/8′′BSP female adapter)
3.Open the gas valve and start sampling.
4.After sampling close the valve and start decompression.
5.Remove the plate.
6.Incubate the plate and count the colonies.
7.Correct CFU number according Feller table.
8.Calculate CFU/m3 (1000 Liter).
Contamination or intoxication of the sampling environment can be prevented mounting the optional exhaust tubing.
