Hitachi Spectrophotometer UH5300 is a double beam spectrophotoneter which provides the bestinitsclass performance with a combination of a longlife Xenon flash lamp and advanced operation using tablet terminals (Ipad). By monitoring the analyte absorption with the spectrophotometer, the reaction rate can be determined accurately. (Do click here to see more) MONTHLY SPECIAL PROMOTION (JAN)
There basically three types of breath analyzers available in the market, which includes semiconductor oxide breath analyzers, fuel cell breath analyzers, and spectrophotometer, breathe analyzers.
The chemical compositions of the treated samples were analyzed using x-ray fluorescence, while the cation compositions of the liquid solution were analyzed with Atomic Absorption Spectrophotometer.

remediation pnsb Utilization of Glyphosate, the Active Ingredient in RoundUp, as a Single Source Carbon (SSC) Media for the Microbes in Quantum Growth‐Light Objective This study is designed to demonstrate that the bacteria in Quantum‐Light, a mixed microbial consortium, are capable of utilizing glyphosate (the active ingredient in RoundUp) as a sole source of carbon. Utilization of glyphosate as a carbon source would imply that these microbes can degrade the molecule into simpler, less toxic forms and that the use of Quantum‐Light should be explored for remediation of glyphosate‐induced phytotoxicity and growth inhibition. Materials and Methods Quantum‐Light was chosen because it contains a consortium of multiple strains of vegetative bacteria that are know to produce enzymes that are capable of hydrolyzing various types of hydrocarbons, a capability that spore‐forming bacteria do not posses. A bacterial media was prepared consisting of disodium phosphate, ammonium sulfate, potassium sulfate, magnesium chloride, sodium sulfide and a micronutrient solution. Four flasks were each filled with 240 mL of this carbon‐free media along with 10 mL of Quantum‐Light. Flasks 2, 3 and 4 had 50 ppm, 100 ppm and 500 ppm, respectively, of glyphosate added to them. Flask 1 served as the control with no glyphosate added. Glyphosate is the only available source of carbon for the bacteria to utilize for growth in this media. Two sets of initial Optical Density (O.D.) readings were taken at 550 nm using both the control and media as blanks. As bacterial cell populations increase, the amount of transmitted light at 550 nm decreases. Therefore, taking absorbance readings on a spectrophotometer correlates with bacterial growth, and is a tool for real‐time measurements of bacterial population increases. The flasks were placed in an incubator‐shaker and were allowed to grow at 37 ºC with constant agitation of 300 rpm. Subsequent O.D. readings were taken at 24, 48 and 120 hours post inoculation. Results As evident in table 1, the absorbance readings of flask 1 demonstrate a decrease in O.D. This means that not only was there no cell growth taking place, but that the bacteria from the initial inoculation were dying off due to a lack of carbon source to support growth.
