    Instruments and analyzers for DHI measurements

    Diffuse irradiance measurements: Diffuse Horizontal Irradiance measurements are performed with a thermopile sensor called Pyranometer mounted on a Sun tracker or shading ring.  When the pyranometer is installed on an automatic sun tracker, the diffuse radiation can be measured in two different ways. Measuring Diffuse irradiance requires an accurate pyranometer with low offset properties. Duirng clear sky conditions the DHI irradiance (W/m2) is less than 20% of the total irradiance. Zero offsets lead to...

    Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

    Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction...

    Determination of aluminium in water by fluorimetric method

    Aluminium is the most abundant metallic element and its salts are widely used as a coagulation treatment agent. At the same time increased levels of aluminium may lead to renal diseases and cause undesirable color and turbidity of distributed water. There are practicable levels of aluminium in water based on optimization of the coagulation process at drinking-water plants: 0.1 mg/L or less for large water-treatment facilities and 0.2 mg/L or less for small. Lumex Instruments provides accurate and selective...

    Waste water treatment plants Screening area: stripping

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment...

    Process water

    Process water is one of the most challenging for analysis instrumentation. Mostly this water is characterized by a certain purity, fluctuating loads, as well as very high salt concentrations. Since any disturbance in water-circuits can lead to an entire plant shutdown, resulting in huge costs, reliable and fast online water analyzers are an essential. Due to the diverse demands of various measurement challenges, application-specific analyzers provide huge advantages against standard analyzers that are used for...

    Machine condition monitoring for biofuels

    Overview

    The use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase. For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. A quick on-site analysis with a portable mid-infrared based analyzer, such as the InfraCal 2 Ethanol Blend Analyzer shown in the photo, can help fuel blenders quickly flag out-of-spec...

  • Quantitative Analysis of Steel Using Laser Induced Breakdown Spectroscopy (LIBS)

    For steel analysis, LIBS is ideal for rapid QC (quantitative analysis and detection of contaminants) for raw materials in production, and to check the elemental composition of finished products. LIBS also offers the ability to analyze slag samples that can lead to the recovery of precious metals lost in the steel production process.
