Calibration Benefits

Calibrating a Shimadzu high-performance liquid chromatography (HPLC) system is important for maintaining accuracy, precision, and reliability in analytical results. Here are 3 benefits of performing Agilent HPLC calibration:


Calibration helps in fine-tuning and adjusting the system to maintain accurate and precise measurements. By calibrating various parameters including flow rate, pressure, detector sensitivity, and retention times, the HPLC system can deliver accurate and reliable results. This accuracy is important for analytical procedures where even the smallest variations can significantly impact the outcome.

Peak Performance

Regular calibration of a Shimadzu HPLC system maintains peak performance. It helps identify and fix any deviations or inaccuracies in the system. This process makes sure that the instrument functions at its peak efficiency, increasing productivity by minimizing downtime due to potential issues that may arise from an uncalibrated system.

Compliance with Regulations

In various industries such as pharmaceuticals, environmental analysis, food safety, and more, adherence to regulatory standards is imperative. Calibration of the Shimadzu HPLC system validates that the instrument complies with industry standards and regulatory requirements. Regular calibration helps in meeting validation criteria and the reliability and traceability of the analytical results, which is vital for quality control and meeting regulatory obligations.

Steps for Calibrating a Shimadzu HPLC System


The preparation phase involves several key steps to guarantee a successful calibration process. To start, the GL-Tec team thoroughly cleans the system components, including the solvent lines, pump, injector, and detector, using a ssolvent to eliminate any residue or contaminants that might affect the calibration. We then prepare the mobile phase by accurately measuring and mixing the appropriate solvents according to the analytical method requirements, maintaining proper filtration to remove particulates. After this, we equilibrate the system by running the mobile phase through all components to stabilize the system temperature and pressure, allowing for consistent performance during calibration.

System Suitability Test

GL-Tec prepares the mobile phase by accurately measuring and mixing the solvent components following the protocol specified in the method. We then equilibrate the system by running the mobile phase through the HPLC columns at the recommended flow rate and temperature for a sufficient duration to stabilize the system. Then, inject a standard solution containing known compounds into the system to evaluate key parameters including retention time, peak symmetry, resolution, and tailing factor. Analyze the chromatogram to confirm that these parameters meet the acceptance criteria outlined in the method. Our team then makes necessary adjustments to the system settings if any parameter falls outside the specified limits. Re-run the system suitability test until all parameters meet the criteria, making sure that the HPLC system is accurately calibrated for subsequent analyses.

Flow Rate Calibration

This calibration process involves determining the actual flow rate of the mobile phase through the system, comparing it with the set or designated flow rate, and making necessary adjustments to achieve the desired rate. It begins by priming the system to remove any air bubbles and stabilize the flow, followed by using a calibrated flowmeter or software-integrated flow rate detectors to measure the actual flow. Any deviations observed are then corrected by adjusting the pump settings or system parameters until the measured flow aligns precisely with the target flow rate

Injector Calibration

Injector calibration involves fine-tuning the injector settings to guarantee consistent and reproducible delivery of samples into the chromatographic column. It involves adjustments to parameters including injection volume, injection speed, and wash cycles, tailored to specific sample characteristics and analytical requirements. Accurate injector calibration not only increases the reliability of analytical results but also minimizes carryover effects, which maintains the system's efficiency and data integrity in analysis.

Column Calibration

Column efficiency, ocharacterized by the theoretical plates, is the separation capability of the chromatographic column. A higher number of theoretical plates reflects better resolution and separation of analytes within the sample. Calibration of retention time maintains precise identification and quantification of compounds by establishing a correlation between the retention times and the compounds being analyzed. This calibration process involves the use of standard compounds with known retention times, aiding in the accurate determination of unknown substances present in the sample.

Detector Calibration

The detector, an important component of the Agilent HPLC setup, requires periodic calibration to validate its response and sensitivity to various analytes. Calibration involves a series of steps, using standard reference compounds at known concentrations to create a calibration curve. This curve aids in establishing the relationship between the detector's signal output and the concentration of the analyte, allowing for the accurate quantification during sample analysis. Regular detector calibration not only guarantees the reliability of analytical results but also maintains the instrument's performance, creating consistency and credibility in analysis across various applications in pharmaceuticals and biopharmaceuticals.


Accurate and detailed records should include system maintenance, calibration, and method development for making sure the reproducibility and traceability of results are accurate. A well-organized documentation process includes all facets such as instrument parameters, column details, mobile phase composition, and standard operating procedures (SOPs). Regular maintenance logs, detailing system checks, repairs, and component replacements, are vital for instrument performance. Documentation also maintains compliance with regulatory standards.
