Thermal Mapping Validation

by Falak Noori Cold Chain Services for Food

Most stages of processing of goods or products within the food or the pharmaceutical industry specify the control parameters for humidity, pressure and temperature. Hence, temperature mapping validation is vital for controlling such processes.

Data is logged and checked through the electronic data logger for hot spots and cold spots. Mapping checks must be made on fully loaded and empty chambers. Most forms of the chambers need this treatment from storage areas and incubators and the warehouses to the autocleves, stability chambers, EtO chambers, dry heat sterilizers, tunnels. Temperature must be done on the quality schedule within the specific circumstances.

In some case, thermocouples can also be used but very often it is quite easier of using the remote loggers for battery powered. In both the case the temperature mapping validation software can get used for collecting before the mapping test, where the calibration can be checked at the time of mapping process or directly at the end.

Basically three mapping check is needed, and if any discrepancy exists in between the tests other mapping test is required to be performed.

Lots of rears need may more temperature mapped points as compared to the small chambers or areas. There are various tools available that can handle around 128 different loggers in one single mapping. The mapping device can be used for the procedure and also posses batch handling interface for gently enhance setup as well as the download times.

The very big chambers and storage areas are sometimes get divided into smaller parts. The mapping feature offer users to develop small map folders and later combine data for making entire picture of around 128 channels.

The accuracy of the data acquisition and the sensors hardware used for performing temperature mapping validation is very critical. Calibration checking and calibration operation processes are indispensible towards regular acceptable practice of validation, irrespective of what sensor one is using. The report of validation must display that sensors, thermocouples, data acquisition and calibration tool have been checked with respect to the traceable grade at a regular interval of time. Thermocouples must be checked after and before any temperature mapping validation study. Thermostats and RTD’s need less frequent checking, basically after very 6 months time.

The software used for the thermal validation can helps in achieving such accuracies by offering user friendly operations, calibration and automated calibration checking process as well as reports. Before the validation study engineer can bookmark all the items of tool in use and can store all acquired data in every validation record. It further helps users to credit audit reports with every single item of the validation tools and calibration.
