Requirements according to quality, control and balance examination General rules on control and checking procedures are content of Health Ministry Regulation of Never touch the standard weights with your hands. Submissions to the compendia for new or revised analytical methods should contain sufficient information to enable members of the USP Committee of Revision to evaluate the relative merit of proposed procedures. Ensure that Operation & Calibration of the instrument is carried out as per SOP. Calibrate the instrument as per SOP. Analytical Scale Calibration using a set of standard weights. After internal adjustment completed, proceed with daily calibration as per calibration sop prior to routine work. The United States Pharmacopeia (USP) General Chapters <41> "Balances" and <1251> "Weighing on an Analytical Balance" aim to ensure weighing accuracy and eliminate unnecessary over-testing for US pharmaceutical manufacturers and suppliers. This can be the tolerance of the nominal value of the weight or it can be the uncertainty of measurement for the weight when applying the actual weight value from the certificate. Obtain at least 3 observations that are taken with a release/removal of the weight from the sensing device. The accuracy of a balance is satisfactory if its weighing value, when tested with a suitable weight(s), is within Change to read: 0.10% of the test weight value. USP General Chapter 1251 "Weighing on an Analytical Balance" is a guideline applicable to balances used in all analytical procedures. Scope: Applicable to all weighing balances except analytical balances. XLII, number 1, 2001). After a six months transition period the new chapters will be official December 1st 2013. Maintain the calibration records. The conventional mass consists of the nominal value of the weight used and the actual difference given on its respective calibration certificate. Scope:This SOP is applicable for calibration of laboratory glassware in Quality Control Department at pharmaceutical company name with location. The scales’ calibration must be validated as per the requirements of a recognized national calibration laboratory. 6.3.8 All volumetric glassware should be calibrated as per SOP of glassware calibration. In addition, they frequently commented that General Chapter 1251 (“Weighing on an Analytical Balance”) no longer represented state-of-the-art weighing practices. The program should include (1) procedures for operating the system, (2) monitoring programs for critical quality attributes and operating conditions including calibration of critical instruments, (3) schedule for periodic sanitization, (4) preventive maintenance of components, and (5) control of changes to the mechanical system and to operating conditions. SOP 8 Modifications. Important note: It is essential that you observe the tolerance limits of the weights used for cal-ibration. Drift check For the calculation of the drift 10 mg weight shall be used. In most cases, evaluations involve assessment of the clarity and completeness of the description of the analytical methods, determination of the need for the methods, and … 3.0 RESPONSIBILITY: All Department Heads 4.0 ... Balance calibration record : XXXXXXX 9.0 ABBREVIATIONS: 9.1 NMT : Not More Than 9.2 RSD : Relative Standard deviation Email This BlogThis! Calibration of Weights and Balances, E Morris and K Fen, Australian Government National Measurement Institute. 3.0 responsibility: microbiologist – to perform the operation as per sop. Execute the Out of Calibration (OOC) in case of calibration failure and breakdown and intimate the … Many of these instruments also have own USP general chapters, for example: •21> Thermometers, 31> Volumetric apparatus, 41> Weights and balances As per USP, balance calibration parameters are Internal adjustments, Linearity, Sensitivity, Repeatability (Uncertainty), and Accuracy, etc. 2. Record calibration data in HPLC calibration format. USP General Chapter 41 (Balances) sets three distinct requirements to be applied to materials that must be accurately weighed. Attachments II: Calibration Record of Analytical Balance Click an Image below is provided (as is) to download Annexure . The USP in general chapter <1241> has stated that the balance drift should be checked daily, before start using the balance with a check weight of say 20 gm for the analytical balances. 1. “Calibration and Verification: Two Procedures. Chapter 1251 describes the following, for example: Balance qualification; Balance calibration… For dissolution assemblies, the mechanical calibration steps in this … Calibration and verification are the most important actions to ensure the correct indication of measuring instruments (K. Sommer et al. They are meant to detect very fine increments of the materials being weighed. An analytical balance is a highly sensitive lab instrument that is designed to accurately measure mass. Calibration weights being used in the Accuracy check must have an accuracy of NMT 1/3 of the balance tolerance for that respective test point. Scope: This sop is applicable to the trolley balance in the department at the plant.. RESPONSIBILITY: Officer production is responsible for verification. 6.3.9 Enter the result in the record and take approval of authorized. Cleaning and Shutdown of the system: After the analysis part is over, purge the system and wash the analytical column with purified water. Air Currents. 5.2.

At present, European and United States Pharmacopoeias (EP [1] / USP [2]) are the main source of information for analytical testing in a Pharmaceutical Quality Control laboratory, thus, should describe main requirements for calibration of equipment. balance performs calibration automatically for greater accuracy. Push the glass draft gently backward and place the butter paper / weighing bottle on to the balance pan center and close the glass draft. For example, due to the permissible tolerance limits for a 200-g class E2 calibration weight, the readout may differ from the actual weight by up to ±0.30 mg. Repeat the intermediate weighing of the weight cart as if multiple weights were being verified. Analytical Balance Calibration Learn how to calibrate the Analytical Balance as Drift check, Performance check and Measurement uncertainty check. The USP requires a simple test – ‘a balance/the test weight’ is sufficiently accurate if the weighed value displayed does not differ by more than 0.10% of the conventional mass of the weight placed on the balance. SOP on Calibration of Weighing Balance. Many leading analytical balance manufacturers provide built-in "auto calibration" features in their balances. Maintain a log of calibration dates and procedures, including reference to NIST-traceable weights or other equipment. balance prior to calibration. this sop is applicable to the operation and calibration of analytical balance being used in quality control laboratory. head - quality control – to ensure the compliance of the sop. cGMP’s speak to analytical instrumental qualification (AIQ), which includes installation qualification (IQ), operational qualification (OQ) and performance qualification (PQ).
