Analytical performance

Measuring range

Adjustable

Detection limit (DL):

Calculated in accordance with VDI 2449, measured on every supplied analyzer during the temperature test (between 5 ... 45 °C) in accordance with VDI 4203.

Depending on sample gas component: see table for standard applications.

For Code ET and FT: in accordance with the requirements of 17th and 27th BImSchV

Smallest recommended measuring range (with 1 m path length)

Depending on sample gas component: see table for standard applications.

The maximum applicable measuring ranges can be found in the table of standard combinations. These can only be applied if the individual process conditions allow it. Please contact the Technical Support from Siemens for checking the applicability.

The following table lists the measuring conditions for standard applications. The listed values for the measuring range and detection limit (DL) are only approximate values. The exact values at the respective measuring point depend on the totality of all influencing variables and can be determined by Siemens for the specific case. Please note that the values for the detection limit and the maximum measuring range refer to an optical path of 1 m. Longer path lengths will improve the detection limit, but not linearly. due to limiting effects such as dust load. The maximum applicable measuring ranges can only be used if permitted by the process conditions such as dust load.

Standard application

Effective optical path length: 0.3 … 12 m
