About Timberline Instruments
Located in Boulder, Colorado, Timberline Instruments has been manufacturing and selling analytical instrumentation since 1987. Timberline offers an ammonia/nitrate analyzer commonly used in agricultural, water, and wastewater applications as well as a line of column heaters and mobile phase preheaters used in HPLC applications.
The Timberline TL-105 is a multi-feature HPLC column heater designed to meet the needs of busy chromatography labs. The TL-105’s microprocessor controlled heating provides stable and accurate temperature control, reproducible retention times, and stable baselines for temperature sensitive detectors such as refractometers, electrochemical, and conductivity.
Mobile Phase Heater
The Timberline Mobile Phase Heaters are used to heat the mobile phase before it enters a semi-preparative or preparative HPLC column. The advantages of operating at elevated column temperatures are plentiful. It has been shown that lowering mobile phase viscosity by operating at elevated temperatures can enhance column efficiency. Controlling column temperature improves retention time reproducibility for individual sample components. Achieving higher column efficiencies and maintaining retention time stability results in higher yields for preparative HPLC systems.
