Gradient HPLC is the ideal technique for analyzing complex samples, while isocratic HPLC is often used for simple mixtures. During gradient HPLC, the strength of the solvent that carries the sample is increased, while in isocratic HPLC, it remains the same. The advantages of gradient HPLC are more specific results in the sample identification and analysis. However, gradient HPLC requires more complex machines that can automatically increase the solvent gradients. Such HPLC machines contain a piece of equipment called a binary pump and can also perform isocratic HPLC.
The BLC-40G from Buck Scientific is the Quaternary gradient version of our BLC-30 analytical HPLC systems with variable wavelength detector.
The BLC-40G HPLC system uses a high-quality, precision monochromator based spectrophotometer for a full range of wavelengths from 190-800nm for selective analyses integrated into a complete LC package.
