Select from our portfolio of high-quality glass 8mm crimp/snap top vials that are ideal low-volume sample vials for 6mm, 7mm and 8mm autosampler trays. Choose from flat or conical base to maximize recovery needed for small-sample injections.
The LEO 1530 VP is capable of a resolution of 2.1 nm at very low electron energies (1 kV) which is of great use for beam-sensitive materials like polymers and insulating surfaces. Also very useful for insulating samples is the variable operating pressure mode which allows insulating materials to be imaged without coating the surface.
Partition Coefficient Compounds that have low K values will tend to partition more readily into the gas phase, and have relatively high responses and low limits of detection (Figure 3). An example of this would be hexane in water: at 40°C, hexane has a K value of 0.14 in an air-water system.
Let’s begin with an example problem: SPME head space analysis of pesticides in tea and follow-up analysis by high speed GC. Anal Chim. Acta 611 (2008) 163 Samples in 10mL sealed glass vials were placed in the MPS-2 autosampler for HS-SPME extraction. Extracted compounds were thermally desorbed from the fiber

Using poor-quality vials (or the wrong vials for your application) can cause sequence problems, unnecessary downtime, expensive repairs, and the loss of precious samples Aijiren vials are the only vials that deliver time and cost savings: • Reduced labor: Our short-thread screw-top vials make screwing/ unscrewing the cap up to 30% faster.
03 Oct 2017. Solvent Choice for GC Injection. I guess we all have our ‘go to’ solvents for our work in GC, and most of the time this will be based on the availability of the solvent and the chemical nature of our samples. Polar samples (analytes) generally need a more polar solvent (methanol for example) and less polar analytes a less polar
Jan 18, 2022 · 【2ml Amber Vial Material】: 9mm Screw Thread Autosampler Vials are made of USP Type 1, Class B Borosilicate Glass with very low expansion coefficient,conforming to USP Type I and ASTM E438, Type I, Class A requirements. It is ideal for containing all injectable preparations with acid, neutral and alkaline PH.
Generally the content, in this case the sample, has a higher thermal expansion coefficient than the borosilicate glass of the laboratory vial. Because of this volume expansion, only ⅔ to maximum ¾ of the total volume of the vial should be filled. If disregarded, the liquid does not have enough space to expand during the freezing process.
clear glass vials are Type 1, 33-expansion glass. Type 1, 51-Expansion Glass More alkaline than 33-expansion glass and is adequate for many laboratory uses. It has an expansion coefficient of 51x10–7 ˚C and is composed primarily of silicon and oxygen, with trace amounts of boron. All Aijiren Technology amber glassware is Type 1, 51-expansion glass.
Jul 27, 2017 · Transfer the combined flow-through from all spin filters and re-distribute into three separate 1-ml autosampler vials. CRITICAL STEP Some volume may be lost in the spin filters. Ensure that the final volume of diluted plasma in the three 1-ml autosampler vials is 780 μl, 780 μl and 530 μl (30 μl more than each of the three sample pickups
