Overview:
Sodium Hydroxide (NaOH), Part Number 90210, is a high-purity reagent used in combustion analysis systems to effectively scrub acidic gases from the gas stream—most commonly carbon dioxide (CO₂) and sulfur dioxide (SO₂)—produced during high-temperature sample combustion.

Function in Combustion Analysis:
In elemental analysis, especially in ONH (Oxygen, Nitrogen, Hydrogen) and CHS (Carbon, Hydrogen, Sulfur) testing, precision is critical. Sodium hydroxide plays a vital role in ensuring analytical accuracy by absorbing unwanted byproducts such as CO₂. This helps isolate the gases of interest and prevents contamination of the detection cell, leading to more reliable measurements.

• Optimized for high-temperature analyzers: Supports accurate measurement in both solid and liquid sample combustion.
• Improves gas stream purity: Removes interfering acidic gases, enhancing signal precision.
• Essential for system longevity: Reduces buildup and corrosion within analyzer pathways.
• Trusted performance: Specifically formulated for use with a wide range of combustion and thermal analyzers.

Applications:
Ideal for laboratories using combustion analysis, this sodium hydroxide reagent supports applications in metallurgy, environmental analysis, ceramics, chemicals, and other industries requiring trace-level elemental detection.
