Buffer solution (potassium hydrogen phthalate), tra

Buffer solution (potassium hydrogen phthalate), tra Specification

Properties
The certified potassium hydrogen phthalate buffer solution is gravimetrically prepared using high-quality reagents at a registered calibration laboratory. It has a pH value of 4.01 at 25 C, measured using a combined glass electrode following a 5-point calibration method. The measurement is made in accordance with DIN 19268 using reference buffer solutions compliant to DIN 19266, NIST, IUPAC, Ph. Eur, and USP. The pH value of the buffer solution heavily depends on the temperature and therefore a constant temperature must be maintained during its use. Application The buffer solution is used as a standard in analytical procedures for the calibration of pH measuring instruments or pH electrodes and as a control for the measurement of pH of other solutions. Features and Benefits Measured and qualified at an ISO/IEC 17025 and ISO 17034 accredited laboratory Directly traceable to secondary reference standard from NIST and primary certified reference standard from PTB Ready-to-use solution available in 30 mL sachets Accompanied with a detailed and batch-specific certificate of analysis (CoA) for an effective quality management system Product label follows the ISO Guide 31 and contains information about ordering number, article description, lot number, safety data, and expiry date Packaging material subjected to comprehensive stability studies as per ISO Guide 35 Accurate up to +/- 0.02 at 25 C

FAQ's of Buffer solution (potassium hydrogen phthalate), tra:

Q: How should the potassium hydrogen phthalate buffer solution be stored for optimal stability?

A: The buffer solution should be stored at room temperature, away from direct sunlight or extreme temperature variations. The packaging material is stability-tested to ensure long-term accuracy, but it is important to keep the sachets sealed until use to prevent contamination or evaporation.

Q: What is the main use of this buffer solution in the laboratory?

A: It is primarily used as a pH standard for calibrating pH meters or pH electrodes. Its certified pH value of 4.01 at 25C makes it an ideal reference for routine calibration and as a control when measuring the pH of other solutions in analytical and quality control laboratories.

Q: When is it necessary to maintain a constant temperature during usage?

A: A constant temperature, specifically 25C, should be maintained during pH measurement or calibration with this buffer. The pH value is temperature-dependent; fluctuations can affect both the accuracy of your instrument calibration and measurement reliability.

Q: Where does the buffer solution derive its measurement traceability?

A: The pH value of the buffer solution is traceable to secondary reference standards from NIST and primary reference standards from PTB. Certification is done at an ISO/IEC 17025 and ISO 17034 accredited laboratory, ensuring international compliance and traceability.

Q: What processes ensure the certified accuracy of this buffer solution?

A: The buffer is gravimetrically prepared using top-tier reagents and measured using a combined glass electrode and a 5-point calibration procedure. Each batch undergoes rigorous testing in compliance with various standards, including DIN 19268 and DIN 19266, with comprehensive documentation provided for each lot.

Q: What benefits are provided by the included Certificate of Analysis?

A: Each batch comes with a detailed, batch-specific Certificate of Analysis (CoA), which outlines the pH value, traceability, lot number, expiry date, and relevant safety information. This documentation supports robust quality management and regulatory compliance in laboratory operations.
