Do not overfill the vials. Fill the vial up to 1/2 to 2/3 of the total volume. Experimental conditions Make sure that the same solvents were used between the runs. Keep the room temperature constant and under 25 degrees Celsius. Acquisition method settings Optimize the draw speed decreasing it down to 50µL/min.

Hamilton maintains a large catalog of replacement syringes for the most popular HPLC autosamplers. Our syringes are handmade with an unmatched attention to detail. The manufacturing process and quality assurance procedures ensure that every syringe we sell will provide superior accuracy and precision as well as cycle life.

The separation was performed on a VP-ODS C 18 column (4.6mm×250mm, 5μm) with the mobile phase of 6.8% phosphate buffer solution (adjusted to pH3.5 with 85% phosphoric acid)-acetonitrile-water (2:43:55,v/v/v) at a flow rate of 1.2mL•min -1. The detection wavelength and the injection volume were set at 233nm and 20μL, respectively.

HT4000E is a flexible HPLC autosampler that can automate your Solid Phase Extraction routine. It is part of HTA’s HT4000 series, which includes lab-automation-ready HPLC autosamplers

The Gastight version of the S-Line syringe is an ideal choice for HPLC sample injections. It incorporates a precision-machined PTFE plunger tip which creates a leak-free seal. With the tight fit in the glass barrel, the tip wipes the interior of the syringe barrel free of sample, minimizing sample carryover.

HTA HT4000L Autosampler Can handle up to 176 2ml vials. Fits all liquid chromatography systems and has the widest range of applications including analytical, prep, UHPLC, IC, nano,

2021/12/21 · In the Auto Additions Editor, specify the vial number from which the sample will be drawn, injection volume, and delay time. Click OK, and the instrument will draw the specified volume of sample from the specified vials in sequence according to the injection setting and Auto Additions setting, and then inject after the specified delay time.

2022/09/27 · Apply the following formula to calculate the maximum injection volume: Maximum injection volume (μL) = [loop volume (μL) + needle volume (μL)] × 0.75 Example: For a system fitted with a 250-μL loop and 30-μL needle, the maximum injection volume is 210 μL. Maximum injection volume = [250 μL + 30 μL] × 0.75 Maximum injection volume = 280 μL × 0.75
