With the increasingly strict requirements for environmental protection in our country, many domestically produced analyzers can no longer meet the measurement accuracy requirements of the market. Siemens ULTRAMAT23 series has launched an ultra-low emission small range analyzer, but it has very high requirements for the working conditions of the measurement site. The sample gas must undergo high-purity pretreatment, temperature, pressure, and flow rate must be treated, and the temperature on site must be stable and maintained at 24 degrees CelsiusAround ℃, there should not be too much fluctuation up and down, and it is necessary to calibrate the zero at regular intervals. It is recommended to calibrate the zero once within 3 hours to prevent drift caused by the analyzer's influence on temperature,

A tube with an outer diameter of 6mm or 1/4 "will be used as a connecting device for storage
In there.
The material used for the tube is PE, FPM, or PTFE.
If the sample gas will flow into an exhaust pipe, please follow the following steps
Point:
·The pressure of the exhaust pipeline must be stable. If not, then it is necessary
Use another independent exhaust pipe or
·Install an attenuation container (>1L) between the analyzer and the exhaust path
·The exhaust pipe should always be placed in a descending gradient manner because
Water will condense inside it.
The gas corresponding to the self calibrating gas/zero gas path must be drawn in through a fine filter. In self labeling
In a constant gas (zero gas), the total amount of gas components measured must be small enough to be

When calibrating, the air must pass through a CO2 absorber (e.g. alkali)

For some specific CO2 ranges (see Section 3), the chopper section should
Synthesis using clean nitrogen or CO2 free gas with an inlet pressure of 3-3.5 bar
Air is used for blowing.

2.4 Gas treatment
The sample gas must undergo sufficient treatment to avoid contaminating the components it flows through
Dyeing. ULTRAMAT 23 is usually installed after the following devices:
·A gas sampling device with a filter
·A sample gas cooler
·An analysis filter (1-2um)
·An external suction pump (sample air path>20m) (see Figure 2-1).
