ANSWER
Sample Manager Alarm band = ± value
- For example, an analytical method has a sample temperature set point of 8°C and an alarm band of 2. The analysis will not proceed if sample chamber temperature is above 10°C or below 6°C.
The Sample Manager starts the injection as soon as the sample chamber temperature is within the ± band of the set temperature. At the start of a run if the temperature is outside of this range the console waits a maximum 60 minutes and a message appears stating "Waiting for Sample Compartment Temperature". The sample manager does not check the temperature of the chamber again during the run.
Column Manager Alarm band = ± value /2
- For example, 40ºC is set for the column temperature and an alarm band of 2 , injections proceed only if the colum module is between 39ºC and 41ºC (±1ºC of the setpoint).
The Column Manager checks if the column temperature is within ½ of the value of the alarm band. At the start of a run if the temperature is outside of this range, "Waiting for Column Temperature" appears while the Column Manager cools or heats to within the temperature range. The console waits a maximum 60 minutes and a message appears stating, "Waiting for Column Temperature". If it fails to reach this range within this time, "Column Temperature Range Error" appears".
During the run if the temperature changes so that it is outside the range of the alarm band, data acquisition stops, the column heater stops operating, and a message stating "Column Temperature Range Error" appears.
The Alliance Range is a ± value.
The Alliance HPLC uses the term Range. Specifies the maximum allowable deviation in sample or column temperature. If the temperature deviation exceeds the range, the alarm condition is triggered. The alarm conditions are also user selectable.
- For example, For a temperature set point is 20ºC and the range is set to 5ºC the Alliance will operate between 15ºC & 25ºC
