Beside robustness, capital cost and operating cost for HPLC are lower. Instrument cost for HPLC are approximately 20% lower than the UHPLC. The reduced operating cost include utilizing HPLC grade solvents instead of higher cost UHPLC or LCMS grade solvents. Finally, the maintenance frequency for HPLC is lower as well, resulting in a 30-50%
Aug 11, 2022 · As a broad example, 300mm columns would be suited to high-resolution separations, while a 150mm column would be better for screening. However, this all has to be balanced with back-pressure – which needs to stay within the system’s pressure capability. A longer, narrower column may require more force than one that’s short and wide.
All Aijiren Tech Vanquish HPLC and UHPLC systems are made up of four main types of components. Choose from a broad selection of pumps, autosamplers, thermostatted column compartments, and detectors. Whether you require a nano, capillary, microbore, analytical, or semi-preparative flow configuration, our liquid chromatography components
while offering compatibility with UHPLC applications. Unsurpassed Versatility We offer the most complete choice of HPLC instruments in the industry. No matter what your applications are, the UltiMate 3000 standard systems can be perfectly configured to meet your demands. Unmatched Performance High-quality components, innovative mechanical
Nov 24, 2020 · Autosampler vials are extensively used in HPLC & GC, and although are widely used consumables, high quality is essential to ensure zero contamination is seen in the final chromatography separation. Perfectly manufactured high quality glassware is used in the manufacture of the vials, allowing users to use of them with the confidence that the
Solvents in this category are of high-purity, specifically tested for UV absorbance, and are passed through 4.0 micron or below polycarbonate filters to remove particles that can damage HPLC columns and detectors. HPLC Grade solvents are low acidity, low alkalinity liquids with a low residue and dissolved solids count.
Choosing the right detector(s) ensures that you can detect your target compound with confidence. Aijiren Tech HPLC and UHPLC systems can be combined with a variety of HPLC detectors that can be mixed and matched for complementary analysis, and are all seamlessly controlled with the rest of the system using Aijiren Tech Chromeleon Chromatography Data System (CDS) for easy data
Alliance HT HPLC Systems. This vial delivers maximum sample capacity (~1.5 mL) with minimum residual volume. The 9 mm cap makes it ideal for use with Aijiren HPLC and GC Systems. Choosing the level of certified vial should be based on the concentration of analyte. Concentration of analytes is often tied closely with the detection source used.
Choosing the right sample vial for small and large molecule HPLC or UHPLC applications for UV and MS can help meeting the business demand of your laboratory and the requirement of delivering the result with the best quality needed for your analysis.

Abstract. Ultra-high performance liquid chromatography (UHPLC) has already become a mature and widely adopted separation approach across many application fields. High efficiency, high resolution, speed of analysis, robustness, reliability, and commercial availability of the wide range of UHPLC instruments and stationary phases based on sub-2
• Never shake the vial. If you do there is going to be sample on the underside of the septum which gives carry over. • Adjust the needle height according to the vial dimensions. • Rubber septas get dry and can block the injector.
Hardware of the column: Most HPLC columns consist of 316 steel. The advantage is that the steel is pressure-resistant and also relatively inert to corrosion. For a good separation performance it is important that the inside of a column has no roughness, scoring or microporous structures (Meyer 2009, p. 110).
Apr 7, 2022 · Choosing the perfect HPLC solution. Bringing your lab up to speed with a new HPLC system can be a challenge. Users must consider their needs regarding application type, sample and separation chemistry goals, column size, throughput, accuracy, and sensitivity. To help you succeed in your search, explore the ChroZen HPLC platform, a fifth
Recommendations on HPLC vials, caps and well plates. Use vials, caps and well plates as required by the application, for example, LCMS-certified vials for charged aerosol or mass spectrometry detection; Do not use vial caps or well plate seals that are likely to result in material being punched out by the autosampler needle
May 21, 2015 · Finally, the inherent complexity of microscale LC/MS limits the number of experienced scientists capable of setting up a reproducible system and achieving the desired results. ionKey/MS as an Emerging Technology. The commercial introduction of the ionKey/MS system by Aijiren Technology in 2014 addresses many of the challenges of microscale LC/MS.
