| dc.description.abstract | Equipment verification and preparation of the documents related to this activity were made. The equipment verification was performed on balances and analytical balances, liquid chromatographs and gas chromatographs. With respect to the balances and analytical balances verification, repeatability, trueness and drift assays were performed. A SOP containing the instructions for the verification, forms to register the primary data obtained from the verification assays, excel sheets to carry out the calculations for the assays, verification notebooks including the form mentioned above and archives to save all the results obtained from such assays were prepared. The performance verification was carried out for two liquid chromatographs. The following verification assays were performed: injector precision, flow rate precision, injector linearity and carryover, detector linearity, noise and drift, flow rate trueness and gradient accuracy. A SOP containing the instructions for the verification, an excel sheet to carry out the necessary calculations for the verification assays and an archive to save the obtained chromatograms and results were prepared for each instrument. For one of the liquid chromatographs a SOP containing the maintenance instructions was written. Two gas chromatographs were verified, one with Thermal Conductivity Detector (TCD) and another one with Flame Ionization Detector (FID). The documents related to the verification and mentioned for the liquid chromatographs were also prepared for these equipments. The following verification assays were performed: flow rate precision, detector linearity, noise and drift, oven temperature precision, trueness, linearity and stability. A SOP containing the maintenance instructions was prepared for both gas chromatographs. The proposed objectives were achieved. | pt_PT |
