The V-670 double-beam spectrophotometer utilizes a unique, single monochromator design covering a wavelength range from 190 to 2700 nm (3200 nm option). The monochromator features dual gratings ...

The V-660 is a double-beam spectrophotometer utilizing a double monochromator and a photomultiplier tube detector.The use of a double monochromator provides high resolution with extremely low ...

Abstract: An investigation on formaldehyde detection using UV-Vis spectrophotometer has been explored in this work. A 37 % aqueous solution of formaldehyde known as formalin is categorized as ...

But because light is massless, it's able to reach the maximum speed limit in a vacuum—about 186,000 miles (300,000 kilometers) per second, or almost 6 trillion miles per year (9.6 trillion ...

They leverage a well-known impediment to laser ion acceleration schemes—namely pre-pulses—to their advantage. Pre-pulses are small bursts of laser energy preceding an intense laser pulse. They ...

A technique to measure the concentration of Penicillium allii conidia in damp chamber experiments by spectrophotometry was developed. A negative linear correlation (R²=0.56) was observed between ...
