Reagent contamination can elevate the background concentration of analytes in a sample, making it essential for laboratories to invest in high-purity acids for trace metal analyses. With limited sample sizes, maintaining low blank levels is crucial for reproducibility. NJbinglab’s SCH sub-boiling distillation systems enable laboratories to produce their own high-purity acids at significantly reduced costs.

The chemical reagents utilized during analysis are a major contributor to analytical blanks. Sub-boiling distillation is recognized as the most effective method for acid purification. This technique employs Wrap-around silicone heating jacket to vaporize the surface liquid at a temperature typically 20 °C below the boiling point.

In conventional distillation, the boiling process generates aerosolized particles, leading to contamination in the distillate. In contrast, the gentle surface evaporation used in sub-boiling distillation minimizes spray or droplet formation, resulting in high-purity acids.

Advantages:

1. Utilizes the same technology as commercial production for ultra-trace metals analysis.
2. Achieves up to 90% cost savings on ultra-pure acids by purifying lower-cost reagent-grade acids.
3. Allows you to purify only the quantity you need, when you need it.
4. Produces up to 90 mL per hour (SCH-III).
