SECTION 1 Introduction Many protocols in life science laboratories require the incubation of samples at specific temperatures. The outcome of these protocols can be dramatically influenced by the accuracy and the uniformity of the incubation temperature between samples during the execution of the protocol. The results of such experiments form the basis of most life science research publications. It is therefore essential that equipment used for the incubation is performing correctly and creating conditions that researchers can reproduce throughout the world. From an equipment perspective probably the most demanding temperature dependent reaction in the Life sciences is the Polymerase Chain reaction (PCR). It requires rapid change in temperature, typically between three set temperatures for approximately 30 cycles a process usually automated by a thermal cycler. For each of these steps the unit must move the samples in the experiment to the next incubation temperature maintaining an even temperature across the samples and delivering them to the next set temperature, accurately, at the same time, with the minimum of overshoot/undershoot. A set temperature can be maintained for as little as 10 seconds and there is therefore minimal time for equilibration of the system before the unit must move the samples to the next set point. This is a considerable task and there is considerable variability in thermal cycler performance between vendors and during the life cycle of an individual unit. The current era of quantitative biology demands ever more detailed analysis of the relationships between samples in gene expression studies and has profound importance in all aspects of health and disease. Consequently it is good practice to verify the correct operation and calibration of the thermal cycler or other incubation instrument. Generally such analysis is conducted off site by a third party. This has the disadvantage of making the instrument unavailable for use for what can be a considerable time period. QTAS systems are high performance multi channel temperature acquisition systems, calibrated, and traceable to the international temperature standard ITS90. Rapid response temperature sensors and flexible probe positioning allow users to monitor the performance of their own machines to troubleshoot applications, transfer protocols between machines and monitor life cycle performance as and when required. QTAS empowers users with the knowledge to optimize their incubations, identify poorly performing equipment and eliminate wasted time and reagent use. Procedures are easily implemented to allow laboratories to fully comply with any regulatory and quality system requirements.

Temperature Probe
Each probe contains a thermistor and is designed to match the well profile of either a 0.2ml thermal cycling block in a 96 well format (well centre to centre is 0.9cm) These probes interact directly with the block of the thermal cycler such that a reading is taken to determine the temperature of the well at any one given time. Each probe has a unique ‘address’ that is determined with a string of letters and numbers. This ensures correct use of calibration parameters for each probe.

Temperature Spread The following screens rotate continuously to provide the Min and Max temperatures and the temperature spread. SPREAD is defined as being the maximum temperature of all probes less the minimum temperature of all probes at any one moment, and where ‘TT:TT’ represents the spread temperature value in °C between the range of 0 °C and 99.9 °C. The spread temperature is updated every second. TEMPERATURE is a real time value taken once per second as default (see page 16). Temperature accuracy is +/0.2 °C using QTAS stand-alone. “R” represents the row identifier (valid range A to H), and ‘”CC”‘ identifies the column (valid range 1 to 12). “TT:TT” represents the temperature value in °C (valid range 0 °C and 99.9 °C)

SECTION 4 Using the Software Once the QTAS software has been opened the user can set some important parameters
Set Sampling Rate The default sampling rate is 1 reading per second (1Hz). This can be changed. In stand-alone mode the QTAS will use whatever sampling rate was last used when it was connected to the PC. This allows the user to change the sampling rate to 10 seconds and run the QTAS remotely, effectively extending the maximum acquisition time of the QTAS (which in standalone mode is limited by data points and battery capacity). 1.
Select Tools and Set Sampling Rate
Sampling rate is shown as default of 1 reading per second, 00:00:00.1 would be 1 reading per 10 seconds and 00:00:10:0 would be 10 readings per second
Set the Date Format The date can be changed to a European or US style. This date is ‘stamped’ onto the trace and in the notes section to comply with GLP and cannot be edited. 1. 2. 3.
Select Format from the Menu Bar Select Date and Set Check the date to set and select OK
