Kjeldahl nitrogen analyzer is a commonly used laboratory analytical instrument widely applied in various laboratories. Users are typically very concerned about the instrument's reliability, accuracy, and after-sales service. However, do you know this key indicator of the recovery rate?

Recovery rate is actually the primary key indicator for Kjeldahl apparatus. Here, recovery rate refers to the "nitrogen recovery rate." Essentially, a Kjeldahl nitrogen analyzer is an instrument for analyzing the nitrogen content in various substances. Because nitrogen exists in various forms in substances, the most important thing for accurate measurement is to recover as much nitrogen as possible. If the recovery rate is too low, it will affect the measurement results. The parallelism of the measurement results will be poor, and the reliability will be low, making them unusable as metrological results. The recovery rate is affected by many factors, including the sealing performance of the distillation system, material selection, condensation efficiency, condensation structure, backflow prevention, anti-bumping capability, and whether venting is performed. Therefore, we must pay close attention to these factors.
