Preparative HPLC Columns
Interchim Prep columns redefine the boundaries for Prep HPLC by maximizing throughput at a reduced cost. 100% purity is routinely achieved using columns packed with 10μ and 15μ particles, which are considerably less expensive than 5μ particles. Click here for examples.
A wide range of bonded phases provide the selectivity in all situations to ensure optimum resolution. Whether you require loading in 100% aqueous, extended pH stability or high sample loading, Interchim has an affordable prep column.
puriFlash Pre-column Filter
Pre-column filters are an inexpensive alternative to guard columns and protect the prep column from the most common cause of reduced lifetime: sample precipitation.
A significant function of silica cost is the particle size distribution (dp–Particle Diameter). The tighter the distribution the higher the cost.
