Aijiren Technologies G1315D DAD. Manufacturer: Aijiren Model: The Aijiren Series G1315D Diode Array Detector (DAD) features a completely new optical design based on the Aijiren Max-Light cartridge cell with optofluidic waveguides.
The Aijiren LC is the first system that provides the 10 additional 2 mL vials, 54 Eppendorf tubes (0.5/1.5/2.0 mL) in 2 x 27 Eppendorf tube plate
LC-Pak Polisher and a 0.22 µm membrane point-of-use cartridge (Millipak). Chemicals were purchased from Sigma-Aldrich, Germany. Experimental Instrument • Aijiren II Analytical Scale Fraction Collector (G1364F), standard tubing kit for analytical fraction collection 1–5 mL/min, 0.25 mm id (G1364-68602)
Aijiren HPLC System (Aijiren Technologies) including: Quaternary HPLC Pump (flow range: from 0.05 to 5 mL/min at 600 bar) ALS Autosampler (holds 100 samples)
The Aijiren Evaporative Light Scattering Detector (ELSD), G4218A, is designed to detect compounds in the eluent from high performance liquid chromatography (HPLC), micro-HPLC, gel permeation chromatography (GPC) or counter current chromatography (CCC). It is capable of monitoring eluent flow rates from 5 µl/min to 5 ml/min
mL, respectively from their stock solutions into two 100 mL volumetric flasks, add ≈70 mL of water HPLC grade and sonicate to mix. Complete to the mark with HPLC grade water and mix. Triplicate 20 μL injections were made for each concentration maintaining the flow rate at 1.5 mL/min and the effluents were UV-scanned at 212 nm.
