The following concentrations of heavy oil can be selected: 5.0, 10.0, 50.0100, 300, 500, 1000 (ppm)

【 Storage conditions 】 Avoid light

Accurate nitrogen content: The nitrogen content of the standard substance is rigorously measured and verified to ensure its accuracy and precision, ensuring the reliability of the calibration results.

Good stability: Standard substances should have good stability and be not easily affected by environmental factors, ensuring the reproducibility of calibration results.

Wide range of content: The nitrogen content of standard substances should cover the nitrogen content range of common samples to meet the measurement needs of different samples.

These substances have been widely measured and validated for their nitrogen content, and can be used to calibrate different nitrogen content measurement methods. In addition, there are nitrogen content reference materials specifically designed for oil products, such as those for light and heavy oils, with nitrogen content ranging from 0.2mg/L to 3000mg/kg.
