HP 1090

The HP 1090 Series HPLC system, introduced in the early 80's, is regarded to be an outstanding instrument in terms of performance and reliability. It was developed with the objective to create an HPLC system with optimized pump performance at 50–5000 Μl/min flow rates and with a new type of detector that could acquire spectral data online. The result was a high-performance solvent delivery system (DR5) and a new UV detector based on diode array detection technology (DAD)  HPLC 1090 system was introduced in 1983 and when it comes to performance and reliability, it is considered to be an outstanding instrument before the introduction of the modular designed HPLC.  HP 1090 HPLC’s pump is being considered as the best pump available in the market today. The delay volume of HP 1090 is comparable to that of the Agilent 1100 series binary pump. The HP 1090 HPLC uses helium for solvent degassing. The good thing about using helium degassing is that there is no need for additional internal volume to be added and changing solvent in one channel only takes a few minutes. HP 1090 injector has a glass syringe for metering devices. This device can be used at low pressures. If the solvent needs to be changed or if an air bubble needs to be removed, it is advisable to use a special wash cycle in order to flush the syringe.
