High performance liquid chromatographic column

Arcus series high performance liquid chromatographic column
??????????
The surface of Exformma using method of silica matrix's unique re hydroxylation treatment, eliminate some lead column efficiency decline in microporous silica gel, formed a very smooth, acidic silanol sites and uniform surface. Arcus series of chromatographic columns including EP-C18, WP-C18.EP-C8, EP-PhenyI (phenyl) and EP-CN (Qing Ji), which is a new technology for the synthesis of chemical bonding. The use of unique bonding technology to ensure that the A rcus series column has excellent separation characteristics, it is difficult to make some of possible separation. In addition to the United States Exformma company's fixed phase complete sealing technology. The Arcus column has excellent shape and longer service life.

PH - wide range high column efficiency
Arcus EP-C18 limit column has the characteristics of high surface coverage and complete sealing, the conventional objective analysis of many organic compounds in a wide range of the C1 8 columns. Our column is undoubtedly an excellent choice. We are on the matrix bonding reaction for a special optimization. Double sealing technology to make our unique chromatographic separation efficiency is the best. Medium pH conditions were analyzed in other C1 8 column, strong alkaline compounds usually have a tailing phenomenon, and analyzed at our C18 phase because it still has good symmetry shape, thus showing the biggest advantage. High coverage characteristics and completely sealing greatly
We improved the stability of chromatographic column, the chromatographic analysis of 1.5 ~ 10 for a wide range of pH value.

- Technical parameters:
99.999％；孔径：100A，120A，150A；比表面积380㎡/g，320㎡/g，200㎡/g。">The purity of >99.999% silica gel pore size: 100A, 120A; 150A; the specific surface area of 380 square meters /g square meters of 200 square meters, 320 /g, /g. Particle size is 3 m, 5 m, 10 m.

The main application:
Drug analysis, food analysis, environment analysis, protein analysis; Normal University, research and analysis,
LC-MS, semi preparative separation and purification and preparation

Arcus EP-C18 limit column
Very high surface coverage and complete double sealing: separation of acidic, alkaline and neutral compounds were in good shape; the best choice for the routine use of C18 column width; pH (pH=1.5 ~ 10) in the range of high column efficiency; has the best separation effect of strong alkaline compounds; excellent batch to batch between columns and the reproducibility of the multicomponent system; from the analysis to the preparation of all the sample quantity scope;

Arcus EP-C8 limit column
High surface coverage and complete double sealing; separation of acidic, alkaline and neutral material has good shape; in a wide range of pH value (pH=1.5 ~ 10) range with excellent chromatographic properties; excellent batch to batch and between columns of reproducibility; retention than C18 classic RP ability the smaller retention capacity and separation selectivity; recommended for hydrophobic compounds and LC/MS instrument; the multicomponent system from the analysis to the preparation of all the sample range has wide applicability

Arcus EP-C18 PhenyI (phenyl) limit column
High surface coverage and complete double sealing with excellent separation effect on the separation of aromatic compounds and polar compounds and difficult separation of drugs; selective phase is different from EP-C18.EP-C8 and EP-CN: excellent batch to batch and between columns of the reproducibility of the multicomponent system; from analysis to the preparation of all the sample range has wide applicability

Arcus EP-CN (Qing Ji) limit column
And the rate of complete double sealing cover bag surface high; low hydrophobic, fast elution of hydrophobic molecules; with unique selectivity for polar compounds: separation of basic compounds including ammonium salt, has a good shape; and the mobile phase has good compatibility and high moisture content; excellent between batch and column asked the reproducibility; in a wide pH range (pH=1.5 ~ 9) has special stability and long service life of the pillars of multicomponent system from the analysis to the preparation of all the sample range has wide applicability
