Description
Nitrate ISE standard solution, 1000 mg/L, is a ready-to-use reference solution for calibrating and verifying nitrate ion-selective electrodes. The preparation is supplied in a practical 500 ml pack suited to routine laboratory calibration work and method checks. With a net weight of 0,6 kg, the bottle is easy to handle on the bench during multi-point or single-point ISE setups. This standard, from manufacturer Mettler-Toledo OnLine, supports laboratories that measure nitrate in water, environmental samples, process streams and quality-control matrices where stable concentration values are essential for reliable electrode response. The 1000 mg/L level is commonly used as a high-range calibration point or as a stock for preparing intermediate standards according to internal procedures. Consistent use of defined ISE standards helps maintain measurement reproducibility, supports electrode slope checks and underpins day-to-day analytical confidence. Apply the solution in line with the electrode and instrument calibration protocol for nitrate ISE determinations.

Questions about ISE standard NO3 1000 mg/L, 500mL
What is this article?
ISE standard NO3 1000 mg/L, 500mL is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
