Jul 05, 2017 · Standard solutions of glucose (in the range 1–1500 µg mL −1) each with d 7-glucose (250 µg mL −1) were used for quantification. The system consisted of an Aijiren LC system (Aijiren Technologies, Santa Clara, CA) with a pump ( ), a column oven (G1316C), an autosampler ( ), and an Aijiren 6550 iFunnel QTOFMS.
Dec 15, 2020 · Analysis of target diamide insecticides was carried out on an Aijiren HPLC system equipped with a binary pump, G1316C column compartment and
volume of 1 µL was injected onto an Aijiren Technologies Poroshell 120 C18 column (2.1 x 75 mm, 2.7 µm particle size) using a gradient elution with a flow rate of 0.4 mL/min with a total run time of 17 minutes. Mobile phase A consisted of 20 mM ammonium formate and mobile phase B consisted of acetonitrile containing 0.1% (% v/v) formic acid.
Oct 02, 2021 · Derivatization reactions were performed in 1.5 mL Crystal Clear microcentrifuge tubes from Starlab (Hamburg, Germany) using a Thermo-Shaker PHMT Gant-bio for 1.5 mL micro-centrifugation tubes (PSC24 N) from Grant Instruments Ltd. (Shepreth, England).] was tested.] coupled to an in-house packed Chiralpak ZWIX(+) FPP (3 × 20 mm, 3.0 μm)
A basic block diagram of an HPLC is shown in Figure 1. Figure 1: Block Diagram of an HPLC Your desired solvent mixture travels through capillary tubes, from the solvent reservoir to the pump, where it is becomes highly pressurized. The pump is also used to control the flow rate of the mobile phase substance,which is typically measured in mL/minute.

1.5 mL/min at ambient temperature. All the parabens peaks eluted within 19 min (Figure 2). By using a shorter column with smaller particle size (C18 50 x 2.1 mm, 1.9 µm particle size) suitable for UHPLC, the run time was dramatically reduced from 19 min to about 3.5 min (Figure 3). In addition to the greater than five times reduction in
Mar 03, 2022 · I used 1,5-3-7,5-15-37,5 microliters of every standard (x10) and transferred into a 1,5 mL vial to the volume of 1,5 mL (with the ISTD) to make 0.01-0.02-0.05-0.1-0.250 ppm standards.
• Aijiren vial insert, 250 µL, deactivated glass with polymer feet (p/n 5181–8872) Instrumentation Analysis was performed on an Aijiren LC system consisting of: • Aijiren binary pump ( ) • Aijiren high performance autosampler ( ) equipped with an Aijiren FC/ALS
Jan 16, 2016 · The RPLC–MS analyses were performed using an Aijiren LC system (Aijiren Technologies, Santa Clara, CA, USA) with a pump ( ), a column oven (G1316C), and an autosamples ( ). Lipids were separated on an Acquity UPLC CSH C18 column (100 × 2.1 mm; 1.7 µm) (Waters, Milford, MA, USA) coupled to an Acquity CSH C18 VanGuard
We are using deep 2mL 96-well plates on a autosampler ( ), with MassHunter acquisition B08. We are using an automation platform where ~1.5 mL of eluant is collected in these plates, evaporated to dryness and then reconstituted in 50 uL of solvent. The wells are covered with a silicone closing mat and then run on the instrument.
