Background of application

In recent years, with the importance of ocean development and application, great progress has been made in the exploitation of ocean water and ocean energy. However, there are still difficulties and unknown areas in the study of ocean water. The composition of seawater is quite complex, and the content of chemical elements varies greatly. It is a mixed solution with complex chemical components, including water, a variety of chemical elements and gases dissolved in water. There are many kinds of anions and cations in seawater, and the concentration difference between them is large, so it is difficult to analyze and determine various ions.

In the analysis of conventional ions in seawater, ion chromatograph is the best instrument with high accuracy and efficiency.

Applied Products

Traditionally, ion chromatograph is mostly equipped in laboratory. It is bulky and complicated to operate. It is difficult to meet the needs of Marine Science examination. Now Qingdao Shenghan Chromatograph Technology Co., Ltd. has introduced a portable ion chromatograph, which is designed to expand the application of ion chromatograph.

IC-P60 is equipped with a surface tablet computer. The built-in battery (external power supply or vehicle power supply) provides more than 4 hours of outdoor use. The specially rapid analytical column can rapidly separate various anions in a relatively short time.

CIC-P60 is suitable for outdoor detection, on-board detection, ocean science examination on-board detection, on-site sample detection of emergencies, etc. It can provide you with timely, efficient and accurate detection results.

Application Method

After simple pretreatment of seawater samples, the target substances were analyzed by portable ion chromatograph.

The seawater samples were treated with silver oxide, and then nitrite (NO2), nitrate (NO3), phosphate (PO4) and sulfate were detected respectively.

Step 1: Get the sulfate ion spectrum

Step 2: Get the spectra of nitrate, nitrite and phosphate
