TOKYO, Sept 1, 2017 - (JCN Newswire) - Showa Denko ("SDK"; TSE:4004) will start selling next month five new types of Shodex(TM) high-performance liquid chromatography (HPLC) columns, namely, "GPC HK-401," "GPC HK-405" and "GPC HK-HFIP404L" packed columns
for gel permeation chromatography (GPC*1: size exclusion chromatography [SEC*2] using organic solvents) as well as "OHpak(TM) LB-805" packed column
for gel filtration chromatography (GFC*3: SEC using aqueous solvents) and "IEC SP-FT 4A" packed column
for ion exchange chromatography*4.
