Teaching ion chromatograph

Nowadays, most universities adopt a centralized demonstration teaching approach, limited to imparting theoretical knowledge. This creates a significant contrast: on the one hand, almost all analytical methods in various industries use chromatographic instruments for analysis, while on the other hand, the undergraduate and even graduate students we cultivate use very little good analytical instruments. As one of the widely used analytical instruments, chromatographic analysis instruments are the foundation that talents in this field must master and proficiently use. In response to the needs of various universities and in order to address the societal demand for talent and the difficulty of employment for college students, the company has developed the EP-50 ion chromatograph specifically designed for teaching purposes.

Beijing Liyuan EP-50 Teaching Ion Chromatography InstrumentProduct advantages:

By using a transparent chassis, students can easily understand the structure of the instrument at a glance.

The detachable structure of the main components increases students' hands-on ability, which helps them to have a more intuitive understanding of the main components of the instrument.

The mobile phase is a low concentration weak alkaline solution, non-toxic, safe, and efficient.

The sample is simple and can be obtained locally, such as tap water or mineral water.

Beijing Liyuan EP-50 Teaching Ion Chromatography InstrumentTechnical advantages:

*Unable to use the Lan Pan structure pump head (independently developed component)

*Seals, including one-way valves and spring-loaded sealing rings (independently developed and produced)

*Six way injection valve (independently developed and produced)

*Bluetooth chromatography data processing software (proprietary software copyright)

*Built in conductivity cell suppressor (independently developed component)

*Circuit control board (independently developed and produced)

Introduction to Instrument Components:

The overall components of the pump, combined with a dual balance wheel structure and imported single valve components of the same quality and gemstone rod sealing components, enable the pump pressure to reach the limit value of 500kg

The built-in conductivity cell suppressor and zero dead body detection unit ensure detection sensitivity and separation. Mold forming ensures consistency in performance.
