This Data Sheet introduces an example of the high-sensitivity simultaneous analysis of inorganic gases and light. hydrocarbons utilizing the Shimadzu Tracera High-Sensitivity Gas Chromatograph system....

With the increasing need to improve the quality of data derived from Gas Chromatographs (GC's) and High Performance Liquid Chromatographs (HPLC's), efforts are underway to increase the quality of the consumables associated with these instruments. This application note reviews three (3) different...

Gas chromatographs (GCs), mass spectrometers, optical spectrometers and photometers are a few examples of analyzer technologies applied in process and plant systems that need sample flow assurance. It is an accepted industry best practice that sampling systems have some type of flow monitor...

Chemist Dick Pfeiffer uses a gas chromatograph/mass spectrometer to analyze compounds in odors collected from a swine production facility. Complaints about nuisance livestock odor in rural areas have become a problem nationwide. Scientists for the U.S. Department of Agriculture's are working...

A technique has been developed that is based on analyzing the effluent from a gas chromatograph with both photoionization (PID) and flame ionization (FID) detectors. The relative molar response per mole of carbon (RMR) of the FID is similiar for many types of carbon atoms e.g. for aromatic...

...discussions on the planning, execution, and analysis. of experiments. The new lab is equipped with modern chemistry instrumentation,. including a capillary gas chromatograph and two Fourier transform infrared. spectrophotometers. The lab was specifically designed and equipped to streamline. workflow...

Monitor vs. their own Gas Chromatograph w/ an ECD detector. NUCON injected a known quantity of SF6 into their HVAC Test System and pulled bag samples from various points. By knowing the flow rates and SF6 starting concentration, NUCON calculated the expected SF6 values at each point. The samples...

A gas-chromatograph mass spectrometer (GC-MS) is a combined analyzer that has superior ability in analyzing organic compounds qualitatively and quantitatively. The first part, gas chromatograph, separates the compounds included in a sample (mixture), then the second part, mass spectrometer, obtains...

...into the polymeric coating as a function of their distribution coefficients. Convection speeds up the process. After a predetermined time, the fiber is removed from the solution and placed into the injection port of a gas chromatograph, where the analytes are thermally desorbed. Alternately, the fiber can...

To replace a gas chromatograph (GC) by continuously measuring the amount of ethylene glycol in diethylene glycol using a near infrared (NIR) ClearView TM fiber optic filter photometer. Background: It is not obvious, even to many NIR practitioners, that NIR can make more subtle distinctions among...
