Analyzer Sample Lag Time Calculation

At its simplest, the analyzer sample lag time calculation is the sum of total volumes (using internal diameters) of the transport tubing and components divided by their flow rates.

lag time = component volume / sample flow rate

Take care to compensate for pressure and temperature in case of gas sample

What is the dew point ?

The dew point is the temperature to which air must be cooled to become saturated with water v***r, assuming constant air pressure and water content. When cooled below the dew point, moisture capacity is reduced and airborne water v***r will condense to form liquid water known as dew. When this occurs via contact with a colder surface, dew will form on that surface.

Devices called hygrometers are used to measure dew point over a wide range of temperatures. These devices consist of a polished metal mirror which is cooled as air is passed over it. The temperature at which dew forms is, by definition, the dew point. Manual devices of this sort can be used to calibrate other types of humidity sensors, and automatic sensors may be used in a control loop with a humidifier or dehumidifier to control the dew point of the air in a building or in a smaller space for a manufacturing process.
