Introduction

Instant Screener is a portable and versatile 3D fluorescence spectrometer. The three-dimensional spectral analysis method uses a matrix that combines fluorescence intensity, excitation spectrum, and emission spectrum to analyze substance content. This instrument can be used as a three-dimensional spectral fluorescence analyzer for rapid detection of non processed samples, and can be used for laboratory and field measurements. As the measured samples do not need to be processed, it reduces a lot of daily work and saves a lot of time, and can provide qualitative and quantitative information related to the measured substance. The advantages of this principle are high sensitivity, strong selectivity, and simple sample measurement process. Instant Screener is a portable and versatile 3D fluorescence spectrometer.

principle

Laser Induced Fluorescence (LIF)

After being irradiated with monochromatic laser, each compound will induce fluorescence, which is the fluorescence reaction of the substance. The shape of the fluorescence reaction curve of different compounds is unique and can be used as a reliable means of self identification. At the same time, the peak of the fluorescence reaction curve can determine the concentration of the compound. Based on the above principle, LIF can achieve qualitative and quantitative analysis of compounds.

To conduct qualitative and quantitative analysis of the test sample using LIF, it is necessary to establish a fluorescence reaction database of known compounds in order to compare the captured fluorescence reaction curves and determine the composition and content of the test sample compounds. The manufacturer provides an intelligent software with a very user-friendly interface, where users can calibrate the compounds they need to determine and establish compound fluorescence data spectra. The manufacturer has established data graphs for some compounds of interest to researchers in multiple application fields. Users can negotiate with the manufacturer to use the existing database when purchasing equipment.At the same time, the database also allows users to supplement it, so that users can achieve the purpose of determining compounds that are not present in the original database. The process of adding new compounds to the database will be completed through a user-friendly software interface with simple operations.The object to be tested is usually composed of multiple compounds. During the measurement, LIF generally uses monochromatic light of multiple wavelengths to excite the sample to produce fluorescence reactions, and captures the fluorescence reactions generated by all compounds. The software will compare them one by one to obtain the results of the compound type and content.

FLUO-SCAN @ software

Multi tasking software has standard and advanced graphical user interfaces for analyzing samples. The system provides control from self-test to diagnosis, and allows users to customize measurement and analysis processes.
Three dimensional spectral analysis compares the spectral data provided by the SFS database with the measured three-dimensional spectral data, and performs decomposition operations and comparative analysis. The software provides all the necessary tools for calculations.
Due to the fact that chemical substances have their own excitation and reflection spectra, different chemical substances have different spectral characteristics. The SFS software library uses the measured spectral characteristics of the substance to determine its content and type. At the same time, it can also store the spectral characteristics of new substances in the SFS library. This way, the measured samples can be compared with known samples in the library.
By using this method, different components of a mixture can be identified and the results of substance content can be given without the need for separate separation for measurement. Another advantage of the database is that the background fluorescence of the measured substance is also measured. If there are fluctuations in the background fluorescence, the software can automatically correct the impact of the background fluorescence on the measurement. The sensitivity and detection level can reach PPM level, and some can even reach PPB level.

expert database

The expert database can separate the spectrum of a certain substance during measurement using SFS, and identify and compare it with the built-in database spectrum. The process of identifying substance separation with this number is the same as the effect of physically separating substances in a mixture and then determining them individually in chromatographic analysis. That's why SFS is called a spectroscopic or mathematical chromatographic analysis technique.
SFS analyzer can quickly measure water samples in the field, replacing laboratory sampling measurement and significantly reducing measurement costs and time. This device particularly meets the demand for efficient and fast measurement of samples

Measurable substance

All substances with fluorescent reactions. Common types include various oils, hydrocarbons, and hydrocarbons; Vitamins and other nutrients; Ingredient substances, organic substances in plants, soil, water bodies, or nutrients and heavy metal elements that have fluorescent reactions after being complexed with organic ions.
