The ordinate is in units of volts and abscissa in minutes. The signals are recorded at a wavelength of 284 nm using a UV detector. Retention time of each peak is marked above the peak and in the tabulated data below the chromatogram details of the retention time, area (as digital units)...
A daylight lamp is term used by marketers to describe lights that are meant to mimic the properties of actual sunlight. They are often referred to as full-spectrum lights, but although they generally produce light throughout the spectrum, they often do not have an even distribution of light ...
The change in absorption is measured by a detector that records the variation in the intensity of the incident light and this information can be used to reconstruct the absorption spectrum that can provide useful information on a sample, such as the HOMO-LUMO separation, a key parameter for opt...
Blocking harmful UV rays Not only that, but they also need to meet your lifestyle and size requirements. If you're new to bright light therapy, all of this can be daunting.This guide will simplify the selection process with critical essentials to consider before choosing a lamp. ...
3. Light therapy Intense pulsed light (IPL) therapy is a noninvasive treatment that uses broad-spectrum light to penetrate the skin. IPL can help address skin pigmentation issues, such as sun spots and melasma, and vascular issues, like redness, broken capillaries and rosacea. "Current c...
When choosing different sunscreen products, consumers take many factors into consideration, including SPF values, broad spectrum claims, UVA-PF value or PA+ rating, and the type of filters used: organic versus inorganic. Organic UV filters are a group of carbon-containing compounds designed to abso...
The 6 Basics of Skin Care No matter what type of skin you have, these tips will keep it looking its best. Use a broad-spectrum sunscreen that blocks both UVA and UVB rays. Avoid direct sunlight, and wear a hat and sunglasses.
This all-natural mineral is used first and foremost as a physical sunscreen. It protects against UVA (broad spectrum) and UVB (wide range). You can combine it with synthetic sunscreens to increase the Sun Protection Factor (SPF). This reduces the possibility of allergies or irritations caused ...
