Mar 01, 2020 · 2. Experimental2.1. Chemicals and materials. All chemicals were reagent grade or higher in quality. Silica microparticles (40–63 μm, surface area 550 m 2 g −1, pore volume 0.8 cm 3 g −1), humic acids sodium salt (technical grade), formic acid (FA), ammonium hydroxide solution (NH 4 OH), ammonium fluoride (NH 4 F), polypropylene tubes and polyethylene frits, high purity steroid hormones
Shimadzu's HIC-ESP ion chromatograph features the same low carry-over, excellent injection precision and low pump pulsation characteristics of the standard HPLC systems, to ensure highly reliable results in quantitative ion analysis. The HIC-ESP system is ideal for ionic samples from environmental testing, pharmaceutical or chemical analysis
Jan 01, 2021 · The HPLC device has a diode-array detector (DAD) ( model) and a column of XBD-C18 (4.6 × 250 mm 5-micro). The particles size was 5 μ m, the injection volume was 100 μ l, the mobile phase was 30% water + 70% ethanol and the flow rate was 1 ml/min.
various species within a sample at the nanogram level. Purpose The purpose of this document is to introduce the user to the routine operation of Aijiren High Performance Liquid Chromatograph ( HPLC) when using either the Diode Array (DAD), Fluorescence (FLD), and Refractive Index (RID) detectors.
The II LC System is a robust high performance liquid chromatography instrument that offers the widest choice of modules for analytical HPLC and entry-level UHPLC. It delivers the performance, reliability, and robustness you need for highest confidence in your daily results. Building on the history of the and series analytical HPLC, the II LC delivers robust HPLC results while providing several ease-of-use features, making it the standard system for
An Aijiren LC System, configured as follows, was used: • Aijiren Quaternary Pump ( ) • Aijiren Inifinty Standard Autosampler ( ) • Aijiren Autosampler Thermostat ( ) • Aijiren Thermostatted Column Compartment (G1316A)
The instrumental linearity was verified within tests on II HPLC-GPC (Aijiren) and SCL 10AVP (SHIMADZU) systems. In the same analytical session, the sequence of injections was repeated 3 times. The average curve was constructed as R t vs Log MW (Excel®) and also as Log MW vs R t (Software HPLC-GFC). In both cases, the
Click the button below to add the Aijiren Sample loop, 100 uL, for Aijiren autosampler and II vial sampler - AA to your wish list.
In this guide we offer you a systematic means of isolating, identifying, and correcting many typical HPLC problems. The important segments of an HPLC system are the same, whether you use a modular system or a more sophisticated unit. Problems affecting overall system performance can arise in each component.
6. Preparation of a sample for analytical HPLC 1) Prepare a ~50 µM solution using HPLC solvent or other appropriate solvent 2) If the sample or solvents have not be previously HPLC chromatographed, filter the sample solution through a 0.2 um filter. You may not inject unfiltered samples. 3) Use volatile buffers ONLY.

Fast and precise gradients – the II Binary Pump is the perfect choice for fast and precise gradients using LC/MS, as well as UV-only systems. Ultralow carryover – the multiwash capability of the II Multisampler cleans all relevant injection parts between runs. This sophisticated, integrated feature flushes the injection needle outside with three solvents, and uses seat backflush procedures to reduce carryover to less than 10 ppm.
Apr 15, 2021 · Disconnect column from detector and run wash solvents into a beaker. 2. Start with your mobile phase without buffer salts (water/organic). Flush 10 to 20 column volumes through the column. 3. Next, use 100% organic (methanol or acetonitrile). 4. Check pressure to see if it has returned to normal; if not, then: 5.
