(8) WindTrax is a software for simulating atmospheric dispersion. Whereas the Gaussian plume approach is a mathematical model used to estimate the concentration of pollutants at a point at some distance from the source of emission.

Taking the headache out of sample loading for UV-Visible/NIR spectrophotometers
HTA S.r.l. have engineered a solution to end the monotony and lost time that users of UV-Visible/NIR spectrophotometers are all too familiar with. The HTI500U has enabled fully automated sample loading specifically for UV-Visible/NIR spectrophotometers
This sample loading automation will not only save time from the rigours manual sample loading, but operators will also experience an increase in productivity, analytical performance and even a minimisation of the carry-over.
The on-board solvent reservoir allows the probe and the whole flow path to be cleaned before processing the next sample, with the option to program the number of washing cycles according to the sample’s physical and chemical properties. Furthermore, sample replicas and calibration curves will be performed more regularly and without complaint because the whole process is carried out unattended.
HT1500U is available in multiple configurations: it supports stainless steel as well as polymeric needle to deal with metal sensitive applications and a wide choice of
fluidics to deal with different levels of flow through cells, including also nano flow through cuvettes, micro cuvettes and macro cells. Different types of tubes are supported too: open or sealed tubes can be hosted to fit any applications. Moreover, the tubes are organised in multiple racks, each of them removable, to enable continuous sample feeding and improved organisation during analyical tasks.
Regardless of the application, whether environmental analysis, routine measurements, advanced research or quality control in production lines, the HT1500U will meet and even exceed expectations in terms of quality and reliability whilst requiring no or just minimal training.
Automating a UV-Visible/NIR spectrometer requires just a preliminary step to make the spectrophotometer suitable for automation using the HT1500U: the standard quartz cell/cuvette must be replaced with a flow cell. This flow cell will be then fully handled by HT1500U and all the samples will be automatically processed. No additional action is required: you can simply leave the HT1500U to do its work and return later for the post-production data management.

New bovine blood pocket meter
HORIBA Instruments introduced the flat-glass sensor technology in 1987 with the launch of the CARDY twin meters. A distinct advantage of the flat-glass sensor is the small sample volume requirement, which led to the development of the compact meters. As the sensor only requires 50 – 100 µL of sample to take measurements, not only large quantity of samples and calibration standards are saved but also the measurement costs are reduced, making the meters cost- effective and indispensable, especially for precious samples analyses.

With the CARDY twin meters riding high in the market, HORIBA launched the LAQUAtwin pocket meters in 1990, and made significant improvements in 2017. The LAQUAtwin series can measure 8 water quality parameters - pH, conductivity, total dissolved solids (TDS), salinity, and ion concentrations of sodium, potassium, nitrate / nitrate-nitrogen, and calcium. Available in vibrant colors, the meters continue to feature flat sensor technology and also offer a variety of sampling techniques which translate to the myriad of applications in which they can be used.
The newest addition is the LAQUAtwin Ca-11C bovine blood iCa pocket meter launched in mid-2020. The meter is developed for easy and quick ionized calcium measurement in bovine blood samples on-farm. Like the other LAQUAtwin pocket meters, the Ca-11C meter has IP67 water & dustproof housing, backlit digital LCD, and replaceable sensor. It is packaged in a rugged carrying case together with two calibration solutions that have electrolyte composition similar to blood, sensor cleaning solution, and wash bottle.
