Microbial aerosol concentrator

Summary

The microbial aerosol concentrator is developed based on the Anderson impact principle. The microbial aerosol concentrator is divided into two parts: the impact chamber and the collection chamber. The impact chamber consists of an impact plate and a receiving plate.

This product complies with the requirements of the standard GB/T 18204.5-2013 Public Place Hygiene Inspection Methods Part 5: Central Air Conditioning Ventilation Systems and the health industry standard WS 394-2012 Public Place Central Air Conditioning Ventilation System Hygiene Specification. The air supply from the central air conditioning is collected and tested for Legionella pneumophila. The large collection flow enables the required particles to be concentrated in the sampler in a short period of time, avoiding the loss of biological activity caused by long-term sampling, and improving the on-site practicality of the sampler.

Main technical indicators

The main gas flow rate (12-120) L/min is adjustable, with an allowable error of ± 5%;

The flow rate of the concentrated gas path (1.5-15) L/min is adjustable, with an allowable error of ± 5%;

Repeatability error of main gas flow rate and concentrated gas flow rate ± 2%

The capture efficiency of biological particles above 3um is greater than 90%.

When the cutting particle size is in the airflow of 100L/min, Da50=1.1 μ M,

When the cutting particle size is in the airflow of 150L/min, Da50=0.65 μ M

When the cutting particle size is in the airflow of 200L/min, Da50=0.43 μ M.

Timing function: 1-99 hours, 59 minutes, and 59 seconds

Dual channel simultaneous acquisition

Manual flow adjustment

L backup adjustable pan tilt table, adjustable sampling head height of 3 meters (or 4 meters optional) according to on-site conditions

High end accessories:

SKC liquid impact microbial aerosol sampler from the United States

Technical parameters:

The special design of the high-efficiency glass impact bottle capture device requires a high flow and sonic air sampling pump to capture microorganisms (such as bacteria, fungi, pollen, viruses) and their by-products such as endotoxins, mycotoxins, and other debris in the air for further analysis.

The liquid impact microbial aerosol sampler has three tangential curved nozzle heads and small holes with decisive or sonic flow. Each hole allows 4.2 liters/minute of air to pass through the combined flow rate, achieving a flow rate of about 12.5 liters/minute. Allow for an effective capture time of at least 8 hours for total or live bioaerosols.
