This is suitable for LC/MS (liquid chromatography / mass spectrometory) analysis. When high sensitivity analysis prevails in many fields, such as drug metabolism analysis and environmental analysis, interference by impurities in reagents and solvents causes a problem on analysis. The reagents and solvents for LC/MS are higher purity products removed organic impurities than HLC-SOL (solvent for high-speed liquid chromatography).

"HLC-SOL" and "Prepsol" are essential solvents for high quantitativeness and reproducibility in chromatography. We guarantee UV absorbance, water content, and so on and provide stable quality products. Especially it is possible to achieve a stable base line during gradient elusion, using gradient grade of HLC-SOL, acetonitrile and HLC-SOL distilled water.

"Ultrapur" has the highest purity in the reagent market. In ultra trace element analysis in the field of semiconductor, pharmaceutical, biochemistry, earth science, environmental chemistry, etc, extremely high sensitivity level is required Ultrapur is filleded in PFA bottles in order to keep it's quality, and ppt level metal impurities are guaranteed for high sensitive metal analysis. After Ultrapur, "Ultrapur-100" in available in the product line secured high purity. A metal impurities of 100ppt level is guaranteed, and HDPE (polyethylene) is used as an dedicated special container.

Recently needs of ultra trace analysis are increasing in the field of environmental, food and water quality testing, and highly qualified and purified reagents are required. Planning to highly purify products with our own equipments for distillation and purification, reagents and solvents are strictly tested by precise analysis.

300 and 5000 times concentration guaranteed products are available in residual pesticides and PCB testing solvents. We provide stable quality product under the GC/MS and PCB conformity testing. 10,000 and 100,000 times concentration guaranteed products are available in dioxins analysis solvents. Dibenza-p-dioxin and debenzafuran of from tetra to octachloro in pre and post concentrated solvents with GC/MS.
