The InfraCal 2 infrared analyser is the choice of experts for measuring oil in produced water; oil contamination in soil; and fats, oils and greases in waste streams. The instrument gives results under 15 minutes and has a reputation for rugged durability. The sampling procedure requires a few simple steps that can be performed by non-technical personnel. The water is mixed with the extraction solvent, shaken, and then presented to the InfraCal Analyzer for measurement. The system has no moving parts, is enclosed in a rugged metal case, and is available with an optional internal battery pack. At a price…
SciMed has over 20 years direct experience of Supercritical CO2 processes. Together with our partners Core Separations, SciMed can offer a complete range of systems, often tailored to suit very specific and one-off design requirements, as well as standard “off the shelf” solutions. All the systems provided by SciMed are modular and can therefore be modified with ease, as and when requirements change. SciMed has supplied numerous systems for all Supercritical CO2 applications including: Reactions in Supercritical CO2 SFE: Supercritical Extraction solutions for solids as well as counter column systems for continuous extraction of liquids Particle generation using CO2 as…
Supercritical fluids are very dense fluids, with superior properties when compared to liquids or solvents. The most commonly used of these fluids is CO2. Unlike solvents, it has a much less harsh impact on the environment. Pumping high density liquid CO2 requires supercritical CO2 pumps, such as the range of high-pressure pumps from Core Separations. Why is Supercritical CO2 So Effective? Once it reaches critical temperature, CO2 remains a gas-like fluid, combining the solvating power of a liquid with the diffusion properties of a gas. Adding small amounts of fluids or other modifiers can improve its solvating properties. Applications for…
Parr Instrument Company offer laboratory scale pressure vessels without mechanical internal stirring. These autoclaves, (referred to as ‘general purpose vessels’), are provided in several convenient sizes and cover a wide temperature and pressure range (shown below) to allow the researcher’s specific application to be carried out. Examples of the uses of these vessels are: Simple organic chemistry pressurised reactions Many organic chemists use our general purpose vessels for carrying out hydrogenations where they heat and stir the vessel on a conventional stirrer hotplate. This is a low cost way of undertaking simple synthetic pressurised reactions while keeping safely as the…
Flame Photometry is the technique of choice for the measurement of sodium, potassium and calcium in all sample types for: • mineral extraction• oil industry• paper industry• pharmaceuticals• soil analysis• utilities• food and beverage• chemical manufacture• fertilisers Sherwood Scientific’s Model 410 Industrial Flame Photometer with digital output (for printer or PC connection), also offers sodium linearization capability to allow higher concentrations of Sodium (<40 ppm) to be directly measured using a single point calibration. This facility can be switched on or off according to the operator’s preference or protocol for sodium determinations. The Model 410 also has sodium, potassium and…
Complimenting our range of Hitachi thermal analysis instruments, SciMed is also pleased to provide a high-throughput multi-sample TGA from Navas Instruments. This instrument is specifically designed for applications in industries that require fast, consistent and reliable analysis of moisture, volatiles and ash content without the need for constant operator attention. Typical areas of applications include: • coal• food• plastics• cement• iron ore• flour• rubber• fertiliser• soil analysis• biomass industries Features• An internal balance prevents the need to remove samples for weighing.• Up to 19 samples with automatic crucible cover placement and removal can be analysed in a single run.• Automatic…
Thermal Analysis techniques such as DSC, TGA and calorimetry are important techniques for the study of Biomass. The techniques can be used to study moisture and volatile content, Loss on Ignition, Pyrolysis rates, gas evolution, evolved gas analysis, and comparison of bio fuels
Sunflower oil is a vegetable oil that is commonly used as main component or supplement in food, such as frying oil, salad dressing, baby food, margarine, or mayonnaise. Furthermore, it is used as an additive in cosmetics, biodiesel, varnish, textiles, and pharmaceuticals. Sunflower oil is among the most widely produced vegetable oils and is obtained from the seeds of the sunflower plant. The production includes the initial oil extraction by pressing (cold or hot) and refining processes such as solvent extraction, degumming, bleaching, and dewaxing. Refining sunflower oil increases its heat stability for frying and cooking purposes but is known…
An important parameter in the site characterization of agricultural cultivation areas is the determination of microbial biomass in soils as well as dissolved organic matter (DOM), which are the basis of the diet of microorganisms. The soil samples are extracted by aqueous salt solutions according to DIN EN ISO 14240-2 “Determination of soil microbial biomass, Part 2: Fumigation-extraction method”. The EOC (extractable organic carbon) or EN (extractable nitrogen) is determined by means of a NPOC/TN measurement.
ultrasound is one of the cleanest, cheapest and most efficient ways to extract compunds from plant and other biological materials including sub-cellular DNA and RNA, juice and oils from plant mateials, botanicals and more recently the new trend in hemp extraction for CBD oil.
New methods for the production of alternative fuels are a growing field of interest. Technologies based on fermentation of starch and sugar, and the transesterification or hydrocracking of plant and animal oil, delivering so-called first generation biofuels, are already well established but linked to limited resources for ethical and ecological reasons. Another promising approach consists of processes based on the conversion of cellulose-rich biomass and waste (second generation biofuels). With the use of biogenic materials for fuel production, the inherently high amount of harmful nitrogen, sulfur and chlorine-containing hydrocarbons that results has to be monitored. Therefore, a strict monitoring of…
Total Nitrogen Determination in Bio-based Fuels According to ASTM D4629 – Standard Test Method for Trace Nitrogen in Liquid Hydrocarbons by Syringe/Inlet Oxidative Combustion and Chemiluminescence Detection The production of alternative fuels becomes increasingly popular, as they provide a way to respond to both, the growing demand for energy and the goal to reduce carbon emissions. In addition to technologies based on the fermentation of starch and sugar, and the transesterification or hydrocracking of plant and animal oil (first generation biofuels), processes based on the conversion of cellulose-rich biomass and waste appear to be promising (second generation biofuels). With the…
