For best performance, minimize the frequency and the amplitude of
changes in the ambient temperature to 1 °C/hour.
According to ASTM E1657-98, the time constant is converted to the
response time by multiplying by the factor 2.2 (i.e., response time =
2.2 x time constant).
The flow cell specifications are as follows:

* There is no exact definition of the light path in capillary flow cells as is for conventional
flow cells. Therefore, you should not use this value for calculating the absorption
coefficient or the detector sensitivity according to the Lambert-Beer law.
