PREPARATIVE HPLC COLUMNS ● Industrial-scale preparative HPLC columns and systems ● High-pressure pulseless pumps ● Complete LC systems equipped with gradient mixers ● Fraction collectors ● Column temperature control ECOM preparative HPLC columns and systems are used in laboratories and production facilities where the isolation or purification of various compounds is required. These systems and columns are suitable for ATEX environments. These instruments are used in many plants around the world and are characterized by perfect functionality, reliability, ease of use, quality workmanship, competitive pricing and flexibility in customization. ECOM preparative HPLC columns and systems can be conveniently combined with other ECOM portfolio – preparative and analytical HPLC systems, detectors, pumps, etc. High performance columns with axial compression ECOM Separchrom PC01 ECOM SEPARCHROM PC01 columns meet the highest requirements of preparative liquid chromatography. They are designed to be used in axial compression mode with a moving input piston. The PC01 columns are equipped with identical pistons on both input and output (biaxial compression is an option). Also, a modification is available, where the lower piston is replaced by a fixed plate. Pistons and plates are equipped with frits. A liquid distributing system is installed under each frit. The design guarantees perfect piston flow and high efficiency – even at a high injection volume – and the simple accessibility of frits for cleaning. Materials and design: ECOM SEPARCHROM PC01 columns are made of stainless steel AISI 316L (tube inner surface is polished to reach Ra < 0.3 µm) with stainless steel pistons and UHMWPE (PTFE on request) sealing rings. The stroke of the main piston is proportional to the hydraulic cylinder used or the length of the flange bolts. The pistons are sectional. The frit (sintered mesh disc 3 µm pore size, 5 mm thickness) with the frit ring can be removed. The output plate in the FE version is made of UHMWPE, and the frit is fixed with a simple frit ring. Column flanges are not welded, but they are screwed onto the column tube. No temperature increases during their manufacture guarantee that there are no changes in their steel properties. The column stand, made of stainless-steel profiles, is included for columns over 100 mm I.D. Hydraulic cylinders fitted onto the upper flange are offered with manual oil pumps as well as with fully automated electric motor-driven devices for column packing/unpacking procedures. Column packing methods: Columns can be packed by the dynamic slurry method, by sedimentation, or by sorbent in a dry state. Accessories: Available in a broad range, such as filling adapters, slurry mixing vessels, slurry transport

PREPARATIVE COLUMNS AND SYSTEMS Columns for Medium-pressure with Axial Bed Compression ECOM Separchrom PC02 ECOM SEPARCHROM PC02 medium-pressure stainlesssteel columns are intended for separation where high pressure is not necessary, but excellent efficiency is still required. Materials and design: Stainless steel tubes, UHMWE piston with stainless steel support and mesh frit. Flow distributor with grooves is incorporated into the piston to guarantee piston flow with nearly zero pressure drop. The frits are simply accessible for easy cleaning. Column packing methods: Columns can be packed by...

Other Parts of the Preparative Column Systems Mobile Phase Delivery HPLC Pumps ECOM Separtrix PP03 Series ECOM Separtrix PP03 are non-pulsating triplex piston pumps for preparative chromatography applications, but they can be used wherever high pressure, precise flow without pulsation, and high corrosion resistance are required. PP03 units are also used for ATEX environments. The pumps are equipped with a unique compact triplex piston head for smooth flow and easy maintenance without risk of leakage between the connecting parts. Back-flushed pistons are coated with a hard and chemically resistant...
