The Agilent 1200 Series Dual Loop Autosampler is a fixed loop sampler with two different sample loops. As a consequence of this design the metering device, also referred to as syringe, is not a part of the solvent flow path from pump to HPLC column. An additional flush solvent bottle is used to rinse this part of the hydraulic path after each injection. In order to minimize carryover, the sampler is equipped with a needle wash function which dips the needle into a wash vial or the wash port. The wash port is fed by a peristaltic pump and can be operated with most common HPLC solvents.
Can be sold as an individual component or as part of a complete stack
Model 3300 ELSD is designed for use with High Performance Liquid Chromatography (HPLC) systems to analyze any sample compound that has sufficiently lower volatility than the mobile phase. Some of its possible application areas include carbohydrates, pharmaceuticals, lipids, triglycerides, underivatized fatty and amino acids, polymers, surfactants, nutraceuticals, and combinatorial libraries. Evaporative light scattering detection eliminates common problems associated with other HPLC detectors. Refractive Index (RI) detectors can be complicated by solvent front interferences, baseline instability, and gradient incompatibility. RI detectors can also have a less sensitive response than ELSD. Low-wavelength UV can suffer baseline drift with steep gradients and also requires that the analyte contains a chromophore. ELSD does not have these limitations. It can achieve stable baselines with multisolvent gradients for improved resolution and faster separations. Also, since ELSD response does not depend on the sample’s optical characteristics, the sample does not require a chromophore or fluorophore for detection.

The Agilent Technologies 1200 Series (G1310B) 1260 Infinity Isocratic Pump is a HPLC workhorse for demanding QA/QC and routine applications, designed to provide virtually pulse-free and stable solvent flow. This delivery principle allows variable stroke volume optimized to selected flow rate. The broadened pressure range with maximum pressure of 600 bar allows the use of small particle size columns, longer columns, or alternative solvents of higher viscosity. Additionally, the G1310B is the ideal pump for GPC/SEC applications where run-to-run and day-to-day precision of retention times are important.
This detector is ideal for analysis of components with limited or no UV absorption such as alcohols, sugars, saccarides, fatty acids, and polymers. It provides high sensitivity, fast baseline stabilization and excellent reproducibility.
