Analytical instruments in water treatment plants, which include optical spectrometers and mass spectrometers like those below, allow for the detection and quantification of organic and inorganic compounds, contaminants and dissolved substances. By using advanced technologies like fluorescence spectroscopy and ionization methods, these tools provide precise, real-time data essential for effective water treatment and environmental research. Their efficiency helps streamline laboratory work, reduce operational costs and enhance overall water management strategies.
HORIBA SCIENTIFIC AQUALOG
The HORIBA Scientific Aqualog is an optical spectrometer that is the gold standard in environmental water research around the world for the study of color dissolved organic matter. It complies with ASTM D8431, and meets the needs of environmental water researchers around the world studying CDOM using fluorescence spectroscopy. Formerly researchers were using scanning spectrofluorometers to slowly acquire a 3D matrix of the fluorescence excitation and fluorescence emission spectra, called an Excitation Emission Matrix. The EEM provides a fingerprint for studying dissolved organic matter; however, it took up to an hour to collect a single EEM profile, tying the researcher to the lab bench for the entire day. The Aqualog vastly improves the speed with which fluorescence EEMs are collected, dramatically increase the dynamic range across which EEM fingerprints are quantitative, and simultaneously acquires absorbance spectra for absorbance and color analysis of nonfluorescent molecules present in water. The technique that the Aqualog employs is an Absorbance-Transmission Excitation Emission Matrix, or A-TEEM.

SHIMADZU SCIENTIFIC INSTRUMENTS LCMS RX
The LCMS RX series of triple quadrupole mass spectrometry instruments from Shimadzu Scientific Instruments are supported by integrated hardware and software technologies to ensure reliable and robust results at lower operating costs, even in the most challenging and dynamic laboratory environments. CoreSpray enhances reliability by increasing gas flow and improving nebulizer coaxiality. This improves the heat distribution of the ionization source, ensuring unparalleled sample ionization, significantly enhancing the reliability of analytical data. The IonFocus electrode is a standard feature across all RX models. It effectively removes matrix contaminants, resulting in lower noise levels, superior data quality and reduced maintenance needs. Enhanced software capabilities autonomously monitor the system, reducing the need for manual intervention.
