In this application note, the authors present a novel, rapid method for identifying low concentrations of oil contamination in process water using Fluorescence Excitation Emission Matrix (FEEM) combined with Parallel Factor Analysis (PARAFAC). This method allows for quick detection and analysis of oil contaminants in process water, offering a practical solution for industries where timely intervention is crucial.

Recently, A-TEEM (Absorbance–Transmittance Excitation–Emission Matrix) fluorescence spectroscopy has emerged as a rapid and effective alternative for BOD detection.

Comparison of the model and actual periodic measurements of THM species in finished water (A) and raw water (B).

This application note describes a rapid, sensitive nondestructive disinfection byproducts (DBP) prediction method using patented simultaneous Absorbance-Transmittance and fluorescence Excitation-Emission Matrix (A-TEEM) spectroscopy.

This application note describes the use of the Aqualog for monitoring regulated Dissolved Organic Matter (DOM) and disinfection by-product issues for drinking water treatment.

This study describes the application of simultaneous absorbance and fluorescence excitation-emission matrix (EEM) analysis for the purpose of identification and classification of freshwater planktonic algal species.

Water travels through the environment carrying dissolved organic matter (DOM), made up of various chemical compounds, which have entered the water column from many sources.

Analysis of Chlorine, Bromine and Iodine in Water using ICP-AES

The analysis of Br, Cl, and I is possible with ICP-AES at low limits of detection due to an adaptation of the instrument. This adaptation doesn't affect the determination of other elements and will generally improve analytical performance for any elemental lines below 200 nm for example, Pb at 168 nm.

Absorbance spectrum of ISS before and after acidification measured with the Duetta

蓝鲸体育直播’s Duetta, a CCD-based dual fluorescence/absorbance spectrometer is a very capable instrument for the determination of Chl A concentration by fluorescence due to its inherent sensitivity and ability to automatically correct for the inner filter effect (IFE), which ensures a very high dynamic range for such analysis. It also can be used to quantify the concentration of the standard stock solution by absorbance, thus eliminating a need for a dedicated UV-VIS spectrometer.

The concern of water contamination from nanoplastics (≤ 1 ?m) is a study receiving close scrutiny from FDA and EPA alike. Nanoparticles can gain access through inhalation, ingestion, or dermal exposure and have greater cellular uptake than those bigger in size. Nanoparticles subsequently pose a greater impact on health.

Brine analysis with the Ultima Expert ICP-OES

The analysis of brines can be easily performed using the Ultima Expert. Low detection limits are obtained due to the ability of the system to perform the analysis without any dilution thanks to the 3 mm i.d. injector associated with radial viewing and the Total Plasma view that minimize matrix effects and enhance sensitivity. The sheath gas device allows perfect short and long-term stability of the system for routine analysis, without any internal standard, recalibration, or drift correction procedure. Good long term stability allows the use of the best plasma parameters and integration times for enhanced performance.

Petroleum and Oil Spill Products

Global drinking water sources remain prone to carcinogenic petroleum product contaminations due to lack of detection capacity at or before treatment plant intake. The Aqualog A-TEEM method provides a reliable optical detection of these compounds at low quantities discriminating from the highly absorbing and fluorescent backgrounds of natural Dissolved Organic Matter (DOM) components.

Measurement of the particle size of soil and sediment sample is a critical part of understanding the geological history of a particular area.

Several different compounds are used for melting snow. The melting and spreading process is a function of particle size.

蓝鲸体育直播 systems have been used successfully for a range of soil and sediment applications. The LA-960V2 is uniquely qualified since the dynamic range is the broadest of any system.

Particle characterization is an important tool for studying current environmental effects related to pollution transport, erosion, and sediment transport.

Characterization of protective mask fibers by Raman microscopy

Due to Covid-19, a wide choice of protective masks are now on the market. These types of masks are distinguished, in particular, by their different efficiencies linked to their filtration capacity. These differences in protective properties have therefore made it essential to characterize the composition of the masks. In this paper, we present why LabRAM Soleil? confocal Raman multimode microscope is the perfect tool for studying the distribution and composition of mask fibers.

In this note, the effect of coagulant choice and concentration on the treatment of suspended clays is analyzed.

Suspended solids are a common impurity in wastewater from industrial and mining operations. In order for water clarity, the suspended solids are often allowed to settle. The duration of these processes is a strong function of the particle size. Thus, if particles can be made to aggregate, the settling process is shorter and the treatment operation is faster and less expensive.

ICP-OES is multielement technique that allows for the fast analysis of more than 75 elements on the Periodic Table in a variety of matrices. This application note examines the analysis of six water and animal food samples.
