Anion exchange chromatography column
Qingdao Shenghan Chromatography Technology Co., Ltd. was established in 2002 and specializes in the research and development, production, sales and technical services of ion chromatography and its core components. It is an enterprise that can achieve mass production of ion chromatography columns.
The stationary phase of the anion exchange column is a positively charged ion exchange resin, such as alkyl amines. When the sample enters the column, the anions will be electrostatically attracted to the positive charge on the stationary phase and are retained on the column. Different anions have different affinities with stationary phases. Anions with strong affinity have long retention time, while anions with weak affinity have short retention time. By changing the composition, pH value or ionic strength of the mobile phase, different anions can be eluted from the chromatographic column in sequence, thereby achieving separation.
SH-AC-6 chromatographic column
A special anion chromatography column for nitric acid digestion samples, using carbonate system leaching liquid. It is mainly used to analyze common anions in samples containing a large number of nitrates. It is characterized by long retention time of nitrates to avoid interference from high concentrations of nitrates on other ions.
Suitable for anion analysis of nitric acid digestion samples in cement and other industries.
SH-AC-7 chromatographic column
A special anion chromatography column was used for rapid analysis, and the carbonate system leachate was characterized by the ability to analyze 6 common anions (Br-, Cl-, NO2-, NO3-, H2PO4-, SO42-) within 5 minutes.
Suitable for industries such as well recording that require rapid analysis.
SH-AC-14 chromatographic column
S2- and CN-special chromatographic columns for analysis, used with an ampere detector.
Mainly used for identification of toxicity of hazardous waste leaching.
SH-AC-16 chromatographic column
A special chromatographic column for polyphosphate analysis, using hydroxide system leachate;
Mainly used to analyze polyphosphates in aquatic products.
SH-AC-17 chromatographic column
Special column for iodine ion analysis by conductance method; hydroxide system leachate can also be used to analyze SCN- and S2O32-plasmons.
It is mainly suitable for the analysis of I-, SCN-, S2O32- in environmental, solid waste and other industries.
SH-AC-18 chromatographic column
SO32-Special chromatographic column for analysis, adopts carbonate system, SO32- and SO42-separation high
Suitable for the separation and detection of SO32- and common anions (F-, Br-, Cl-, NO2-, NO3-, H2PO43-, SO42-) in the detection of environmental particulate matter and water quality.
SH-AC-19 chromatographic column
The thin tube diameter anion chromatography column uses a hydroxide system leachate. Its characteristics are that the tube diameter is thin, the flow rate is low, the high pressure resistance, and the signal response value are high. It can complete the analysis of seven common anions (F-, Br-, Cl-, NO2-, NO3-, H2PO4-, SO42-).
Suitable for trace analysis of drinking natural mineral water, packaged drinking water, domestic drinking water and other industries.
