UHPLC Instrumentation for Nano, Capillary and Micro LCThis calculated sensitivity increase is actually a scale factor between the conventional and miniaturized LC application, with flow rate as the best example.
Why do we use UV-Vis spectroscopy?UV-Vis SpectroscopyUltraviolet-visible spectroscopy is absorption spectroscopy and it uses visible regions of the electromagnetic spectrum. The effect perceived color of chemicals and in this spectroscopy, molecules undergo electronic transitions....
Why do we use ethanol, and not water to remove the OpaDry coating from pills?Chemical Properties:To approach this question, we'll need to understand the properties of molecules and how they affect their solubilities in aqueous and organic solvents. ...
These samples are then sent to a state-of-the-art, in-house analytical laboratory dedicated to the use of advanced analytical methods and technology, including HPLC (high-performance liquid chromatography), gas chromatography, mass spectrometry and much more. These tests are performed by highly ...
In this way, we don’t rely on chromatography, but solely the mass spectrometer’s ability to realize the analytes and the LC to provide the eluent. Now that we have the physically set up the system to tune, we set up the software to do just that. The parameters we will tune ...
Ion chromatography is another popular technique to measure the number of ions left after soldering. It is also an easy way to detect the amount of weak organic acids from the flux. A humid, use environment can lead to failure. One challenge to ion chromatography is that different methods will...
The exceptional quality of IDT products starts with the equipment we use during synthesis. While many oligo manufacturers use the same general synthesis of protecting groups as described in Figure 1, nearly everything IDT uses to produce an oligo is made within our own facilities. We formulate al...
What to do: Use the bowl to trace a circle onto a piece of white cardboard and cut it out. With the ruler, divide it into six approximately equal sections. Color the six sections with the colors of the spectrum as shown. Try to color as smoothly and evenly as possible. ...
Kids will be WOWED with this hands-on, fall science experiment where they will learn about chromatography for kids in this Why do Leaves Change Color Experiment. This why do leaves change color for kids is such a fun leaf activity that preschool, pre-k, kindergarten, first grade, 2nd grade...
As depicted in Text S5, the residual PMS concentration was determined, and some samples were analyzed by ultra-performance liquid chromatography (UPLC) using an ACQUITY UPLC system (Waters, Milford, MA, USA). Proton nuclear magnetic resonance (NMR) spectra were recorded on a Bruker AVANCE spectro...
