6.1

Calibration and validation

Bottle mode allows you to perform calibration, validation, and system suitability test
procedures on the PAT700. Proper calibration of the analyzer is critical to maintaining
optimum instrument performance. You may perform such functions automatically with the
Onboard Automated Standards Introduction System (OASIS™) using the touch-screen
interface. This method minimizes user intervention by using a prepackaged standards kit with
RFID technology. You may run calibration, validation, and system suitability test procedures
immediately or schedule them to run later.
This chapter provides general instructions on performing calibration and validation
procedures. Refer to the specific Standard Operating Procedure (SOP) for detailed
instructions.
• Calibration assures the accuracy of instrument's readings at regular intervals.The
• Validation ensures the accuracy of the calibration by challenging the calibration with
• Calibration and validation involve running analyses of one or more standards and

Four functions are available under bottle mode: run standards, grab sample, excursion mode,
and unload bottles.

Onboard Automated Standards Introduction System (OASIS)

The PAT700 Onboard Automated Standards Introduction System (OASIS) is used for
performing standards tests, grab sampling, and excursion sampling. Through the bottle mode,
various bottle test functions can be selected. The OASIS system is automated through the
use of RFID technology (see
tags are installed in the system, the analyzer uses RFID technology to read and transmit data
about the standards to the analyzer. This system eliminates the need for manual data entry.
Although equipped to perform automatically using RFID tagged standards, you may also use
bottles without RFID tags by manually entering the standards data when prompted by the
analyzer.

TOC calibration protocol

Select up to three levels (250, 500 and 750 ppb) of a sucrose standard. For maximum
accuracy, the procedure allows up to three analysis replicates per standard.

TOC validation protocol

Perform a single-point or multi-point validation of the TOC calibration using up to three levels
of sucrose validation standards.
