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.

WesTech offers a holistic approach to surface water treatment for potable use. Depending upon the raw water quality, the flow rate, and operational preferences, WesTech can provide conventional flow, combination treatment units, packaged systems, high-rate processes, or even customized solutions.
The method is intended for determination of hesperidin and naringin using capillary electrophoresis technique in order to reveal adulteration of juices. These components are tested in citrus juices, concentrated juices, nectars, juice-containing beverages, and fruit sauces that are produced primarily from oranges, grapefruits, tangerines, lemons, and limes.
GCLs can be used for decorative ponds, golf course water features, fish ponds, water reservoirs, and wastewater lagoons. Their self seaming installation requires no specialized equipment, and their self-healing characteristics promote long life and high performance.
The method allows determination of herbicides classified as phenoxycarboxylic acids, specifically: 2,4-dichloro-- phenoxybutyric acid (2,4-DB), 2,4-dichlorophenoxypropionic acid (2,4-DP, Dichlorprop), 2,4-dichloropheno-- xyacetic acid (2,4-D), and phenoxyacetic acid in samples of natural, potable and treated waste water by capillary electrophoresis.
When automobiles are manufactured, each vehicle is painted by spraying a mist (paint mist) onto the car body and other parts. This process is referred to as the paint booth, and it ensures the beautiful finishing of car bodies and components and rust proofing. The excess paint that does not to cling to the car body and parts in the paint booth falls to the floor and is collected by water. This water is used as recycling water after removing the paint with water treatment chemicals.
Pulp and paper processes use a large amount of water that must be treated for production and reclaimation purposes. Effectively treating water from these processes ensures the disinfection of microorganisms that would otherwise breed in the environment and affect product quality and quantity.
The shredding of wax and wax plates is not a simple task for the shredding machine from various points of view, because even at a small increase of the temperature the wax becomes a viscose mass. However, the wax is also a raw material that has to be recycled. The Mercodor shredders are best suitable for shredding of wax, wax plates and wax-containing products.
Mercodor shredders for shredding of Commercial waste are being widely used. So the crushing of Commercial waste will reduce the waste volume and thus will be reduce costs, at the same time the shredding of Commercial waste will protect the environment. Mercodor special engineering is your partner for professional shredding of Commercial waste.
Along with the creation of a standardized SDS, it is just as critical to ensure a seamless process to create hazard labels. Our hazard label software systems is integrated with our SDS authoring engine. The easy-to-use functionality ensures that any updates to the SDSs are reflected on all hazardous labels, ensuring accuracy and consistency.
As a specialist in the evaporation technique GIG Karasek has its complete solutions, from laboratory test, used in many international projects to the overall system. All systems offer high process reliability, thus providing maximum possible system availability.
In the crushing of batteries, a particular attention is necessary, which in turn is a challenge for the used crushing machines. However, in the course of raw materials recycling, the crushing of batteries is an important step and serves at the same time for protection of the environment.
GCER - Teammate Chemical Industries; Experiences and projects with the chemical industries in Tunisia and abroad have enabled us to offer our customers a wide range of products and solutions related to the chemical liquid container for the development of this industry. We have developed a solid experience in the design and manufacture of pipes and storage systems designed to convey aggressive and corrosive chemical fluids and it is precisely at this level that distinguishes the characteristics of GCER applications.
The crushing of salts such as, for example, hardness salts, salt dispensers, but also rock salt, is a great challenge for the crushing machine from various points of view. On the one hand, the salts are very hard, but already in the presence of a very small amount of a liquid they dissolve and mix with the liquid. The Mercodor crushers are best suitable for crushing of salts of any kind such as, for example, crushing of rock salts, but also for crushing of salt dispensers and hardness salts. We at Mercodor will...
