The following conditions must be <br />verified prior to entering data into LIMS <br /> . <br /> • Appropriate analytical methodology was used, based on th@ sample matrix <br />and analyte concentration <br /> . <br />' • Instrumentation was functioning properly during sample analysis. <br /> • Quality control sample checks were analyzed at the proper frequency and <br /> quality control sample checks met performance criteria requirements. <br /> • Analysis was completed within the method-specified holding time. If <br /> holding times were exceeded, immediately inform the appropriate laboratory <br /> section supervisor. <br /> • All analytes were quantitated within the calibration range Qsamples were <br /> diluted into calibration range, if necessary). <br /> • Matrix interference problems were verified. Corrective action (reanalysis, <br /> dilution, matrix modifiers, etc.f was taken to minimize or eliminate the <br /> interference, where possible. <br />' <br /> • Method specific analytical requirements were achieved (y-int@rcept values, <br /> correlation coefficient values, surrogate recoveries, etc.}. <br /> <br /> • Calculations, dilution factors, and detection limits have been verified. <br /> If any of the requirements listed above for method-specified requirements) <br /> were not met, do not enter this data into LIMS. Instead, immediately inform ~ <br />' the appropriate laboratory section supervisor. The laborartory section <br />supervisor will then determine what corrective action is required <br /> . i <br />' 14.2 LIMS Data Entry Requirements <br />
