3. Laboratory automation workstation workflow 1. Experiment preparation: Determine the purpose and requirements of the experiment, formulate an experimental plan, and collect and prepare materials, equipment, and reagents required for the experiment. 2. Sample processing: Preprocess, label or extract the samples to be tested for subsequent experimental analysis. 3. Instrument operation settings: Set instrument parameters according to experimental requirements, such as temperature, time, light source, wavelength, etc., and perform instrument calibration and verification. 4. Automated equipment operation: Place the sample into automated equipment, such as automatic pipetting workstations, liquid chromatographs, mass spectrometers, etc., and set the required operating procedures. 5. Data collection and analysis: After the automated equipment performs experimental operations, it collects corresponding data through sensors, detectors, etc., and converts the data into visual results or digital data for analysis and processing. 6. Result recording and report generation: Record the experimental results, including instrument parameters, operating procedures, data results, etc., for subsequent review, analysis, and report writing. 7. Data storage and management: Store, back up and manage experimental data. You can choose to store it on a computer, server or cloud platform for subsequent review and traceability. 8. Cleaning and maintenance: After the experiment, clean and maintain the instruments and equipment used to ensure the normal operation and service life of the equipment.
