Manual Supercritical Dryer SCD-350M
Supercritical CO2 has gas-like diffusivity and liquid-like solvation power under supercritical condition
(temperature >31.26oC, and pressure >7.29 MPa). With its low viscosity and low surface tension,
supercritical CO2 can quickly penetrate into the mesopores and micropores of a solid matrix. Therefore,
the rate of drying with supercritical CO2 is much faster and efficient than that of traditional methods (by heating or freezing). During drying process, the sample could be “conditioned” with ethanol and then
supercritical CO2 solvates the “ethanol/water” complex and have the water carried out subsequently.

All NEW Supercritical Fluid Extractor SFE-650M
SFE basically extracts organic compounds from a tough matrix. A good example is the extraction of additives and/or monomer from a polymer matrix.
Traditional method is Soxhlet extraction. It takes about 48 hours and lots of energy (hence heating cost) while SFE may take just 1 hour. With SFE, the extracted “Soup” is very clean and ready to be used. While the
“Soup” from Soxhlet would take a long time to post-process before it would be used. Wasted organic solvents from Soxhlet has to be stored and processed by waste management organization. This costs lots of resources (money, time and labor). All these (environmental friendliness) could easily convince you that SFE is the way to go!

Application note includes: Excitation-emission plot showing three biofluorophores (NADPH, tryptophan and riboflavin) that are used to identify biological particles using fluorescence. Ambient number concentrations and number distributions for particles falling in the WIBS ABC category (fluorescence in all channels). Note correlation with ascospores counts (fungal spores) measured independently using an off-line method. Particle counts measured by a WIBS-4A sampling cladosporium (fungal) spores in a laboratory chamber. Fluorescent particle concentrations plotted as a function of relative humidity for ambient measurements in Raleigh, North Carolina associated with a frontal passage. Concentrations of super-micron fluorescent particles classified as biological compared to model predicted concentrations of bacteria and fungi over a cross-section of the southern United States. Particle concentrations in each WIBS-4 channel measured inside a building containing numerous lecture halls and classrooms at the University of Manchester in the UK.

Solutions based on Selected Ion Flow Tube Mass Spectrometry
SIFT-MS accurately identifies and quantifies volatile compounds. The analysis occurs through a process of chemical ionization in a reaction tube (flow tube).
To analyze volatile compounds, a sample is introduced into the flow tube at a precisely controlled rate. Inside the flow tube reagent ions react with volatile compounds present in the sample. This reaction forms product ions, which are analyzed by a quadrupole mass spectrometer and particle multiplier. The result is spectra, which instantly identify and quantify volatile compounds. Volatile compounds can generally be detected and quantified within the 10 to 250 m/z mass range.

ColiMinder® Measuring Principle
How high is the level of fecal contamination in a water sample?
The classical method is utilizing the growth of bacteria (E.coli/Coliforms) and the number of colonies formed, to determine the level of contamination.
The ColiMinder® is using the metabolic activity (specific enzymatic activity) of target organisms as a measure for how many living E. coli are present per volume of sample to determine the level of contamination.
The measurement technology used in the device is fluorescence spectroscopic detection of
E. coli-specific enzymatic activity. The classical method to measure bacterial contamination of water is using a fundamental property of bacteria, their growth and ability to form colonies in a culture medium, as measured variable and measuring method.

PhysiChem Instruments Introduction

A new generation of physisorption analyzer –iPore Series
The physisorption instrument is a complex system consisting of vacuum, temperature control, pressure measurement, air intake, and degassing modules. We try our very best to minimize errors of these modules as any error came of any of these systems will cause observable deviations in the results. Physisorption analysis is a method for measuring the specific surface area, total pore volume and pore size distribution of porous materials. Cross-sectional area of the inert gas (such as nitrogen) is used as a scale for the measurement. Therefore the amount gas adsorbed on the surface of porous materials reflects the properties of the materials. Since the calculation is based on the Ideal Gas Law, good control of temperature and pressure is our design objectives for acquiring accurate results. Long hours sample analysis time (up to 48-72 hours) requires stability of the instrument. Power failure should be avoided to the fullest extent and we try to avoid this by supplying an UPS.
