A novel system for sedimentary organic carbon isotope sample preparation

摘要

A new type of isotope preparation system was designed with excellent accuracy, high degree automation and high security. In view of the existing equipment with automation low degree automation, poor safety, much long preparation time and low precision of the sample preparation problems, a series of improvements were introduced, such as the automatic sampling device, contact valve, vacuum auxiliary system, gas meter and digital dashboards. It was found that the instrument finely designed had the characteristics such as high accuracy, automation and security. Combined with the sample detection device, the preparated sample had excellent detection results. Meanwhile, a set of standard operating procedures had also been formed. Furthermore, the sample preparation process was briefly discussed.
