    Spectrometry for Sample Analysis: Technique Overview

    Several options exist for determining the composition, concentration, and purity of a laboratory sample. Among the most commonly used techniques are Ultraviolet/Visible (UV/Vis), Infrared (IR), and Atomic Absorption Spectrometry. Each technique is capable of providing some or all of these pieces of information you need. In addition, each of these instruments is capable of interrogated different types of samples, including air, industrial chemicals, biological fluids and foods. Therefore, selection of an appropriate technique for analysis of your sample is essential in obtaining the desired data.

    UV/Vis Spectrometers

    Several types of UV/Vis spectrophotometers exist, however they all operate on the same basic principle. In short, discrete bandwidths of light are passed through a sample. “Visible” light energy can be seen by humans, while its close neighbor, ultraviolet, cannot. In the entire electromagnetic spectrum ranging from hi

  2. How are UV Rays Beneficial to Aseptic Environments?

    How are UV Rays Beneficial to Aseptic Environments?

    The sun naturally “cleanses” the earth’s surface with ultraviolet energy. Due to conditions like sun burns and skin cancer, we are most familiar with UVA and UVB rays, but there is actually a third classification of ultraviolet energy called UVC. These rays contain the highest energy, making them the most dangerous type of ultraviolet light. Fortunately, Earth’s atmosphere acts as a protective layer and UVC energy does not penetrate our ozone layer. These harmful rays, however, are industrially produced as a beneficial source of UVGI (ultraviolet germicidal irradiation). Keep reading to find out why.

     

    How does UVGI work?

    UVGI is a technique that utilizes short-wavelength ultraviolet light to kill microorganisms. Since UVC energy is not naturally present within our planet’s atmosphere, earth-bound microorganisms, such as germs or viruses, have not evolved to naturally defend th

  3. 7 Cleanroom Cost Cutting Strategies

    7 Cleanroom Cost Cutting Strategies

    Increasing energy costs don’t have to deplete your budget. Having an appropriate cleanroom design and selecting practical equipment can control energy-related expenses. Below are seven cost-efficient tactics to help you maintain your cleanroom performance and productivity without breaking your budget.

     

    1) How big should your cleanroom be?

    Let’s start with the decision of modular versus bricks-and-mortar. With a modular room, building permits are usually not required, and if your business moves to a different location, modular rooms can be disassembled and re-built in the new space.You should also consider the size of your cleanroom. Design the floor plan and height of the ceiling to meet your specific needs. Keep in mind the future you visualize for your controlled environment. Initially larger spaces are more expensive to construct and maintain, but if your facility plans on future expansion,

  4. Movers & Shakers: what mixer for my application?

    Movers & Shakers: what mixer for my application?

    Instrument options abound for preparing, incubating, washing, or chemical fixation of samples using kinetic motion. Lab mixers that include orbital shakers, vortexes, rockers, rollers and rotators are all offered in a variety of configurations (capacity, speed, duration, slope and more). These common lab instruments have been a necessary component of basic experimentation and sample preparation for decades; almost as long as chemists have understood the impact of motion.

    The diversity of these mixing instruments is second only to the media and containers with which they are used. Thus, one must consider not only the procedure being performed, but also the nature of the samples used. Here we discuss this equipment and their most common applications to assist you in selecting the correct solution.
