Lead (Pb) Monitoring Applications

Parallel Synthesis is a technique widely used by researchers to speed the discovery of new compounds and screen for optimal process conditions.  In the pharmaceutical industry, Parallel Synthesis speeds the discovery and development of potential drug candidates.  Early practitioners coined the term `combinatorial chemistry` to describe the synthesis of large libraries with diverse chemical structures screened in mass for potential biological activity.

The most important measurement parameter is irradiation. Since PV systems are becoming ever larger, the accuracy of the irradiation measurement is increasingly important for the efficiency of the system. Wind cools the temperature of the module and must therefore be included in the efficiency calculation. Precipitation leads to contamination or covering (snow). With increasing temperature, the performance of the solar module decreases. Therefore, it is important to measure the temperature of the solar module in addition to the air temperature.

Overview

Cities and towns are often responsible for maintaining critical assets such as water and wastewater treatment facilities and power generation plants. Oil analysis on this critical equipment as part of a robust maintenance program is a very cost effective way of failure avoidance. Additionally, greater emphasis on environmental conservation and a focus on delivering critical services while operating under reduced budgets leads municipalities to activate these programs. Spectro oil analysis solutions are used by many municipalities to monitor treatment plant gearboxes and backup diesel generators, and avoid costly lubrication mixups.

SF6 (sulphur hexafluoride ) or air is used as an insulation gas in circuit breakers . Excess moisture in these gases causes arcing, which can trip the circuit breaker and cut off power to the distribution network. More seriously, such arcing can lead to physical damage of equipment and, on occasion, death of plant operatives (please ask for our case study on circuit breakers).

Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.

This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.

Although applications in this area advance, there is still a clear demand to get new portable and versatile analysis systems for many different application fields such as pollution in environmental or waste waters, monitoring nutrients in agricultural or horticultural water as well as general process control in chemistry industry. Because of the number of enviromental analysis required, there is a need for screening and monitoring measurements of these compounds at contaminated areas.

Traditional monitoring techniques are typically based on laboratory analysis of field-collected samples that require considerable effort and expense, and the sample may change before analysis. Moreover, the equipment currently available is too large and expensive and it cannot be made portable.Alternatively, microfluidic and electrochemical sensor technologies can contribute to the development of new portable monitoring systems, complementing standard analytical methods for different environmental monitoring applications.In this way, the decentralization and integration of all those typical analyses is the paramount importance in order to reduce cost, simplify the analytical process and make more accessible these technologies to end-users. The development of portable, robust, and accurate Lab-on-a-Chip systems to monitor priority compounds such as contaminants, explosives, chemical warfare agents, inorganic and organic ions is a demand of modern society. Portability allows analyses to be carried out outside of the laboratory, minimizing the risk of contaminating the sample and leading to a faster response time at a lower cost.

Thus, MicruX solutions and technologies open the gate to develop portable and esay-handly Lab-on-a-Chip devices in order to improve pollutants in-situ analysis in a very economic and efficient way.

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 of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.
