High Pressure Liquid Chromatography (HPLC)


The Hewlett Packard 1100 Series HPLC consists of an online vacuum degasser, a binary pump, a standard autosampler, a diode array detector and a fluorescence detector. The high-pressure mixing gradient pump gives an excellent retention time precision and baseline level separation. An autosampler is freely accessible to different vials with precise programmable injection volumes from 0.1 µL to 1.8 mL. The diode-array detector has 1024 diodes and a programmable slit to optimize wavelength resolution, while the deuterium and tungsten lamps ensure the highest light output from 190 to 950 nm.

The fluorescence detector has the ability to simultaneously monitor and measure up to four signals in a single run. The 1100 Series modules and ChemStation software are combined into well-integrated systems that meet a wide range of analytical applications from pharmaceutical research to environmental study.
The 1100 Series units located in EQAL are used for quantification of algal and plant pigments in natural water and lake sediment samples. The instrument is also used to detect and quantify toxins produced by cyanobacteria.
