Clean Chemistry technology has been incorporated in the SRC through the design of its sample vials. Unlike closed-vessel digestion, where samples are digested in individually pressurized vessels, with SRC the reaction chamber itself is the pressure vessel. Samples are weighed into simple autosampler-type vials and placed in a rack.

Jul 01, 2020 · Low Expansion Coefficient - 9mm Screw Thread Autosampler Vials are made of clear Type 1, Class A Borosilicate Glass with very low expansion coefficient. It shows excellent chemical resistance to acidic and neutral solutions, due to its relatively low alkaline content even to alkaline solutions.
Features: LOW EXPANSION COEFFICIENT - 9mm Screw Thread Autosampler Vials are made of clear Type 1, Class A Borosilicate Glass with very low expansion GUIDELINES FOR AUTOSAMPLER VIAL SELECTION Some utilize robotic arms to pick up a sample vial; some use tray rotation while The lower the coefficient of expansion the better the glass can handle.
Isobutylene concentrations in samples was 28.3 m3 in volume with an airflow capacity of 0.47 m3 s-1. collected by the BiB method were highly reproducible as The air stream fed to the biofilter had a variable concentration demonstrated by the very low coefficient of variability (CV ) of roughly 300-400 µg L-1 ethyl acetate.
- A setpoint of -2 mm will sample 1.6 mm from the vial bottom - Range is -2 mm to 30 mm • Example uses: - Samples with sediment (although properly filtering the sample is ideal) - Sampling from higher in the sample vial in liquid-liquid extractions - Small volume sampling • Exercise caution when using sample offsets in combination with vial
Because of their low coefficient of expansion and their high resistance to chemical attack, borosilicate lab glassware is used to manufacture such lab items as beakers, flasks, kettles, test tubes, ground joints and other scientific products. With proper care, they will withstand nearly all temperatures used in normal laboratory use.
volatiles in the sample matrix and promote their transfer into the headspace, resulting in lower K values. However, the magnitude of the salting-out effect on K is not the same for all compounds. Compounds with K values that are already rela-tively low will experience very little change in partition coefficient after adding a
Dec 05, 2014 · Helium (purity: 99.9999%) was used as carrier gas. At the headspace autosampler the incubation temperature was set to 313 K for 45 min (30 min for oxygen detection) with a head pressure of 30 psi. The autosampler was connected to the GC via a heated transfer line with a temperature of 393 K. The headspace syringe was set to 488 K.
Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including autosampler vials, general-purpose vials, and vial accessories for sample collection, storage, and
autosampler vial products were tested and the pH shifts measured. In theory the highest quality of vials is expected from 33 type vials, as the coefficient of mean linear thermal expansion is the lowest for the basic tubes used for vial manufacturing, as well as the hydrolytic resistance acc. to ISO 719, acid resistance acc. to DIN
