Oct 1, 2016 · First of all, we proved that the variation of peak areas between consecutive injections was much more critical with highly concentrated mAb samples (up to 80mg/mL), while the SEC measurements of commercial mAbs having concentrations below 5mg/mL were reliable.
Sep 12, 2022 · Table 1.5.1 1.5. 1 lists the base quantities and the symbols used for their dimension. For example, a measurement of length is said to have dimension L or L 1, a measurement of mass has dimension M or M 1, and a measurement of time has dimension T or T 1. Like units, dimensions obey the rules of algebra. Thus, area is the product of two lengths
Nov 10, 2022 · Vials Use only Aijiren vials, the shape, and the material is optimized for maximizing instrument precision. 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.

For optimal results, you need to control several parameters during packing. These packing parameters are specific to a given resin as well as the column type and dimension. This guide summarizes parameters for small-scale HiScale™, XK, and Tricorn™ chromatography columns with Capto™ and MabSelect™ resins. DOWNLOAD NOW
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.
The II Vialsampler combines sample management and column handling in a single autosampler module. The Vialsampler injects from up to 132 standard 2 mL vials and has a pressure rating of 600 or 800 bar. Options and upgrades are available for sample cooling and heating from 4 to 40 °C. An integrated column compartment is also
There are a lot of factors to consider when selecting a chromatography vial. Aijiren Tech offers a large selection of 0mm 10-425 HPLC vials and closures, including HPLC vials, inserts, caps, and septa to suit your analytical needs. Vial Dimension: 11.6*32mm Vial Volume: 1.5-2.0ml Cap: Plastic open/solid cap Septa: Non-slit, Pre-Slit, PTFE/Silicone
Rev. Sci. Tech. Off. Int. Epiz., 40 (1) 3 Page 3 of 27 (cut-off values and thresholds, definition of positive and negative results and result interpretation). The assessment and optimisation of test parameter performance is critical for
Jan 21, 2016 · The chromatographic performance is evaluated by separating seven conventional anions, organic weak acids, et. al. The results indicate that PDA-PEI shows higher reactivity than PDA due to the present of abundant amine groups. The introduce of PDA-PEI coating makes PS-DVB microspheres can be quaternized under mild conditions.
Chromatographic techniques represent one of the most significant sources of analytical data found in today's pharmaceutical laboratories. All of the chromatographic techniques produce data that must be acquired, interpreted, quantified, compared, reported, and finally archived (see Chapter 21). Whether the analysis is qualitative or
The LC-2030C NT is an integrated high-performance liquid chromatography system which prioritizes easy-to-use features for a smooth analysis experience. The intuitive touch-screen interface and stable column performance over many continuous injections ensure reliable data every time, whether you are an HPLC beginner or an expert.
important because it is used to ensure that the fraction marks line up properly relative to the peaks. Peak resolution — although there are some mathematical definitions for this in chromatography, it is the relative distance between the apexes of two neighboring peaks. Width at half height (WHH) — a measure of the separation efficiency.
No vial is placed in inventory without passing cleanliness and performance testing for consistency resulting in a certified, 100% defect-free vial you can trust. Use these two accessories together to maintain the integrity of your sample components as well as protect your system from particulate contamination.
