Varian, Inc. has announced the introduction of its 940-LC liquid chromatograph. It can be used both as an analytical HPLC and for scaling-up flows to work with larger capacity preparative scale columns to isolate, purify and collect moderate quantities of components of interest in a sample.

Semi-preparative HPLC is typically used in pharmaceutical, food and agriculture, and academic research laboratories as well as in laboratories studying or refining natural products and specialty chemicals.

According to company, the Varian 940-LC saves time and valuable sample material by allowing chromatographers to optimize their separations and collect purified components on the same instrument. Delivering flow rates of 0.025 ml/min up to 200 ml/min, the 940-LC is suitable for use with both 4.6 mm ID analytical columns and, following a linear scale-up, 2” semipreparative columns.

Offering analytical and semi-prep capabilities in a single instrument reduces the expense, maintenance, and complexity of employing separate systems. The 940-LC automates the transition from analytical to semi-preparative flow rates without the need to change plumbing or configurations, reducing the possibility of errors and subsequent losses of materials.
