New Features and Capabilities: Ability to create and use custom test solutions that pipette like your non-aqueous samples (such as high concentrations of Glycerol) on your MVS and optimize more liquid classes on your liquid handler. ...
Raman spectroscopy is a very powerful technique because of its inherent macromolecular specificity requiring minimal or no sample pretreatment, ability to measure aqueous samples, flexibility in sampling configuration, and suitability for automation. ...
Determination of chromium in complex matrices is a notorious challenge, as interconversions between species may occur during sample preparation, making quantification very difficult. In a recent research study published in Journal of Agricultral and Food Chemistry, Rahman et al. performed speciated isotope dilution mass spectrometry (SIDMS), as described in EPA Method 6800 ...
Novum tubes can be automated using a liquid handler and can also be run using a cost-effective vacuum manifold to run 12 or 24 samples at once for increased throughput over traditional LLE. The original plate format is ideal for high-throughput clinical, forensic and pharmaceutical research analysis. ...
The multi N/C series of Analytik Jena consists of a number of powerful analyzers for the fully automated and simultaneous analysis of TOC, NPOC, POC, TC, TIC and TNb parameters in aqueous samples. It is, for example, used in the analysis of drinking water and sewage, water utilized for pharmaceutical purposes or cleaning validation, surface water through to the ...
Modern Water plc (AIM:MWG), the owner of leading water technologies for the production of fresh water and monitoring of water quality, today launches the UVI4000, an ultraviolet (UV) digester that provides a quick and easy way for the UV treatment of aqueous samples. The UVI4000 eliminates organic compounds found in aqueous ...
The sensitive method works for most aqueous samples, including soil extracts and low levels in seawater. ...

Contaminating microorganisms are likely to be introduced with the larger organisms and during sampling, and Most detrital processing is carried out by the sediment microbial community, but this community is not clearly described or measured by this ...
Scope 1.1 This test method covers the determination of the pH of unused engine coolants and antirusts, and used or unused aqueous dilutions of the concentrated products. Note 1—Antirusts in solid form are not included in this test method. Note 2—It is believed that this procedure gives all the information required for determining the pH of ...
It is intended for the analysis of ethanol samples containing between 1.0–20 mg/kg of existent or potential inorganic sulfate and 1.0–50 mg/kg of inorganic chloride. 1.2 The values stated in SI units are to be regarded as standard. ...
Detection limits by direct aspiration may also be extended through sample concentration, solvent extraction techniques, or both. Where direct aspiration atomic absorption techniques do not provide adequate sensitivity, the analyst is referred to Practice D3919 or specialized procedures such as the gaseous hydride method for arsenic (Test Methods D2972) and selenium (Test ...
Scope 1.1 This test method covers the determination of soluble lithium, potassium, and sodium ions in brackish water, seawater, and brines by atomic absorption spectrophotometry. 1.2 Samples containing from 0.1 to 70 000 mg/L of lithium, potassium, and sodium may be analyzed by this test method. 1.3 This test method has been used successfully with artificial brine ...
Scope 1.1 This test method covers the determination of soluble barium ion in brackish water, sea-water, and brines by atomic absorption spectrophotometry. 1.2 The actual working range of this test method is 1 to 5 mg/L barium. 1.3 This test method was used successfully on artificial brine samples. It is the user's responsibility to ensure the validity of this test method for ...
