An arsenic AAS (Atomic Absorption Spectroscopy) standard is a solution of a known concentration of arsenic, used to calibrate and verify the accuracy of AAS instruments during analysis. These standards are typically prepared from high-purity arsenic compounds and are available in various concentrations and matrices, often in diluted nitric or hydrochloric acid. Here's a more detailed description:Key Characteristics:

Concentration:Arsenic AAS standards are available in various concentrations, with common examples being 1000 mg/L (1 g/L) and 1 mg/mL.
Matrix:The standards are often dissolved in a dilute acid, such as nitric acid (HNO3) or hydrochloric acid (HCl), to maintain stability and prevent precipitation. The concentration and type of acid used can vary depending on the specific application and manufacturer.
Purity:High-purity arsenic compounds are used in the preparation of these standards, ensuring reliable and accurate results.
Traceability:Many arsenic AAS standards are traceable to reference materials like those from NIST (National Institute of Standards and Technology), ensuring a known and reliable source for the arsenic concentration.
Physical Properties:Common physical properties include a clear, colorless liquid appearance, and a density close to 1 g/cm3 at 20C.
Safety:Arsenic standards are hazardous and require careful handling due to the toxicity of arsenic. They are often labeled with hazard symbols like GHS05 (corrosive) and GHS08 (health hazard), and a "Danger" signal word.

Applications:

Calibration:Arsenic AAS standards are essential for calibrating AAS instruments to accurately measure arsenic concentrations in samples.
Quality Control:These standards are used to verify the accuracy and precision of AAS measurements, ensuring reliable results.
Elemental Analysis:AAS standards are widely used in various fields for the determination of arsenic concentrations in diverse samples like water, food, and environmental samples.

Example:A common example is a 1000 mg/L arsenic standard in dilute nitric acid (0.5 mol/L HNO3), which is clear and colorless, according to Loba Chemie. This standard can be used to calibrate AAS instruments for measuring arsenic levels in different matrices.

Precise Calibration for Atomic Absorption Spectroscopy

Our Arsenic Standard is meticulously formulated to provide exact results for AAS applications. The 1000 ppm concentration and 99% purity allow for reliable calibration whether using Flame or Graphite Furnace methods. The solution ensures optimal performance and repeatable analyses, making it a trusted choice among laboratories and industries focused on arsenic detection and quantification.

Safe Packaging and Handling

Packaged in robust plastic bottles designed for safe transport and storage, this arsenic standard is classified as toxic yet non-explosive. Users are advised to wear gloves and avoid direct contact during handling to prevent exposure. The product's solid, water-soluble form simplifies preparation and minimizes the risk of spillage in routine laboratory use.

FAQ's of Arsenic Standard for AAS:

Q: How should the Arsenic Standard for AAS be prepared for laboratory use?

A: To prepare the Arsenic Standard for AAS, dissolve the white powder in distilled water as specified for your calibration procedure. Ensure accurate dilution according to your analytical requirements, and always wear gloves during handling.

Q: What safety precautions are recommended when using this product?

A: Users must wear protective gloves and avoid any direct contact with the substance, as it is classified as toxic. Handling should occur in well-ventilated areas, and care must be taken to avoid ingestion, inhalation, or skin exposure.

Q: When is this standard typically used in analytical processes?

A: This arsenic standard is primarily used during the calibration and quality control phases of Atomic Absorption Spectroscopy, especially when quantifying arsenic levels in environmental, industrial, or research samples.

Q: Where should I store the Arsenic Standard to maintain its integrity?

A: Store the product in its original plastic bottle at room temperature, away from direct sunlight and sources of heat, to preserve its quality and purity throughout its 12-month shelf life.

Q: What are the benefits of choosing an industrial grade, water-soluble arsenic standard?

A: Industrial grade standards ensure rigorous purity (99%) and consistency. The water solubility allows for easy preparation and reduces the risk of incomplete dissolution, enhancing analytical accuracy.

Q: Can this product be transported safely, and what are the relevant hazard considerations?

A: Yes, the arsenic standard can be safely transported as it is non-explosive, though it is toxic. It should be shipped in accordance with hazardous material regulations and should always be kept in its secure plastic bottle.
