Antimony Standard Solution 1000 mg/L (1000 ppm) 100ml

SKU : I-9076.0100

CAS : 10025-91-9

Formula : Sb

Grade : Standard solution

Antimony (Sb) 1000 mg/L (ppm) standard solution is primarily used as a calibration reference in analytical chemistry for instruments like Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma (ICP) to accurately measure trace antimony levels in environmental, industrial, and pharmaceutical samples, ensuring quality control and compliance with safety standards. It acts as a stock solution for preparing lower concentrations to detect Sb in water, alloys, electronics, and flame retardants, helping monitor pollution and product purity.

An antimony standard solution of 1000 mg/L (1000 ppm) is a precise chemical mixture used as a reference material in analytical chemistry.

Standard Reference: It provides an exact, certified concentration of antimony (Sb) that serves as a known baseline for calibrating sensitive laboratory instruments, such as those used in Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma (ICP) analysis.
Accuracy and Traceability: The solution is typically a Certified Reference Material (CRM). This means its concentration is highly accurate and traceable to a national metrology institute, such as the U.S. National Institute of Standards and Technology (NIST). This traceability ensures that measurement results in one lab can be compared reliably to results in another lab globally.
Units of Measure:
- 1000 mg/L: This is the precise concentration, indicating there are 1000 milligrams of elemental antimony in every liter of solution.
- 1000 ppm: “Ppm” stands for “parts per million”. For dilute aqueous solutions, 1 mg/L is approximately equal to 1 ppm, so these terms are often used interchangeably to express the same concentration.
Matrix: The antimony compound (e.g., antimony(III) chloride or antimony trioxide) is dissolved in a specific acid matrix, often dilute hydrochloric acid (HCl) or nitric acid (HNO₃), to ensure stability and solubility. The specific acid concentration is crucial for the solution’s chemical properties.
Application: It is essential for determining the presence and concentration of trace amounts of antimony in various samples, including environmental (water, soil) and industrial materials.
