Our planet is a complex and delicate system; each element is interconnected and affects the other. In this scenario, environmental analysis plays a critical role in comprehending and preserving the environment. By dissecting its intricate details and monitoring water, soil, and air, it is possible to evaluate pollution levels and formulate efficient management approaches.
VELP provides solutions to support worldwide laboratories that process samples reliably and quickly according to International Standards and Regulations. We offer application-oriented instrumentation, optimized methods, and comprehensive service and application assistance.
SAFE, PRECISE AND FAST COMBUSTION ELEMENTAL ANALYZERS
Elemental analysis provides valuable insight on many frontiers, such as determining Total Carbon (TC) and Total Organic Carbon (TOC), which yields comprehensive insights into soils and sediments and influences decisions related to crop management, fertilizer application, and soil amendments.
CN 802 Carbon Nitrogen Elemental Analyzer
To provide laboratories with the highest precision, versatility and ease of use, we set a new bar for accuracy with the
CN 802 elemental analyzer, the VELP
robust and flexible combustion analyzer. It is
the ideal solution for high-sample productivity laboratories, since it provides
fast and accurate results, eliminating the need for aggressive chemicals or time-consuming analysis steps.
Additionally, the
CN 802 has been specifically designed for
routine long-term determination of TOC in any sample matrix, while the
innovative and maintenance-free HighSensIR Detector enables the analysis of high-weight and volume samples to obtain accurate results when testing inhomogeneous samples and those with low concentration levels.
EMA 502 Elemental Analyzer CHNS-O
For occasional TOC analysis, VELP offers the EMA 502, a very sensitive micro elemental analyzer designed for simultaneous carbon, hydrogen, nitrogen, and sulphur determination by combustion analysis, and oxygen determination by pyrolysis.
The high degree of automation, low operating cost, easy design and flexibility in determining the elements make it suitable for a large variety of applications, including a few numbers of daily samples for TOC determination in soil and sediments.
NDA 702 Dumas Nitrogen Analyzer
Nitrogen is another element which plays a key role in
environmental analysis.
For the
determination of Total Nitrogen in environmental samples, such as
soil and
sludges from wastewater treatment plants, an
elemental analyzer is needed since we have to consider the value of
ammonia, nitrite, nitrate, urea and organic nitrogen.
To meet this challenge, VELP offers the
NDA 702, a macro analyzer which enables the
analysis of high weight and volume of inhomogeneous solid, semi-solid, and liquid
samples simultaneously, to obtain the most accurate results. The
NDA 702 offers
precision, repeatability, and efficiency, thanks to the lowest LOD in the market.
MAXIMUM VERSATILITY WITH THE KJELDAHL METHOD FOR NITROGEN DETERMINATION
At the heart of
Nitrogen analysis also lies the
Kjeldahl method, a gold standard technique renowned for its precision, reliability and versatility, as it can handle an extensive range of samples, including environmental ones.
In environmental fields, this method can be used to perform:
▶
Total Kjeldahl Nitrogen (TKN) in water and wastewater;
▶
Nitric Nitrogen to monitor
nitrogen levels in soil and fertilizers;
▶
Phenols Pollutants in water bodies;
▶
Volatile Acids as indicators of soil health;
▶
Cyanides assessment of toxicity in agricultural runoff.
With decades of expertise in analytical instrumentation and a commitment to innovation, VELP offers a comprehensive range of
Kjeldahl nitrogen analysis solutions designed to meet the diverse needs of laboratories worldwide.
FAST AND COST-EFFECTIVE SOLVENT EXTRACTION FOR THE DETERMINATION OF POLLUTANTS
Solvent extraction is crucial for identifying pollutants and contaminants, not only for complying with current legislation but also for the well-being and future of living beings.
The SER 158 is the perfect solution for safe, fast, accurate, and reliable determination of extractable matter. It helps laboratories reduce analysis time by up to five times (compared to traditional Soxhlet) and maximizes solvent use by recovering up to 90%.
Some of the applications for which the SER 158 can support laboratories include:
▶ The determination of PCBs in sediments or the determination of oil and grease in wastewater. PCBs, acknowledged as persistent and bio-accumulative contaminants, are produced by industrial processes. They tend to amass in soil and sediment, yet can contaminate water across extensive distances through atmospheric and sea currents.
▶ The determination of oil and grease in wastewater. Domestic and industrial wastes, as well as sludge, contain an amount of oil and grease that should be properly disposed of as they cause damage to aquatic organisms, plants, animals, and human beings. Oil and grease create a layer on the water's surface that decreases dissolved oxygen, reducing biological activity. Then, knowing the quality and concentration of oil and grease helps in the proper design and operation of wastewater treatment systems.
SMART AND EFFICIENT BIOCHEMICAL OXYGEN DEMAND (BOD) AND RESPIROMETRIC ANALYSIS
VELP designs and manufactures advanced solutions for BOD and Respirometric studies, for laboratories working in water and wastewater quality control, biological waste treatment plants, renewable energy production and all environmental laboratories dedicated to the study of the effects that plastics and other pollutants have on water and soil.
The BOD Sensor is designed for laboratories working with BOD applications. The RESPIROMETRIC Sensor performs any kind of respirometric study thanks to its powerful pressure sensor suitable for both aerobic and anaerobic analysis.
AEROBIC RESPIRATION TEST
- Biochemical Oxygen Demand – BOD
- Assessment of the effects of disinfection on BOD determination
- Biodegradation of Monomers
- Biodegradability of plastic materials in an aqueous medium.
- Soil respiration
ANAEROBIC RESPIRATION TEST
- Biochemical Methane Potential – BMP
- Denitrification analysis
JAR TEST AND LEACHING TEST FOR WASTEWATER ANALYSIS AND TREATMENT
Flocculation and
leaching are two fundamental processes for safeguarding human health and the environment. Flocculation is used to remove suspended particles from water, improving its quality. Leaching is used to determine the solubility of a material, simulating its behaviour.
VELP offers a comprehensive range of tools for Jar and Leaching tests, known for their quality, reliability, and ease of use. VELP products are designed to meet the diverse needs of laboratories, ensuring maximum
resistance to chemical and mechanical corrosion and the best
reproducibility.
