  • Improving color dosing for liquid detergents using Coriolis mass flow meters

    Improving color dosing for liquid detergents using Coriolis mass flow meters Why is some laundry detergent blue? Many household liquid laundry detergents are easily recognized by their distinct blue color (sometimes also green or purple). Besides playing an important role in brand recognition and customer appeal, these colored dyes also serve a more functional purpose. […]

  • Fast, flexible leak testing for single-use bioprocessing

    How do you know that your bioprocessing is free from costly leaks or integrity failures? Leak testing of single use systems can now be accomplished easily and quickly with an Alicat Scientific Whisper Series Mass Flow Meter.

  • Optimizing supercritical CO2 solid-liquid extraction with Coriolis mass flow

    Optimizing supercritical CO2 solid-liquid extraction with Coriolis mass flow CO2 is used in all kinds of industrial applications; for example, liquid CO2 is commonly used as a cooling agent and solid CO2 (dry ice) as a dairy preservative. Here, we focus on the industrial applications of supercritical CO2 (sCO2). What is sCO2? A supercritical fluid […]

  • Aerobic and anaerobic wastewater treatment

    Bioreactors are now a common part of wastewater treatment. Alicat’s revolutionary differential-pressure based mass flow controllers allow for extreme flexibility in mass flow control and the response times needed to make this process efficient and cost effective.

    External ion gauge vacuum control system

    External ion gauge vacuum control system Research projects involving isolated chambers with decomposing organic components often use rotometers. The external ion gauge vacuum control system uses a special configuration of the Alicat single valve pressure controller. Alicat’s External Ion Gauge Vacuum Controller was designed specifically for the vacuum coating industry. This innovation circumvents the low […]

    Mixed gas re-metering

    Mixed gas re-metering Some production processes gain substantial quality and yield improvements through mixed gas re-metering. Historically, there have been few technologies that can support mixed gas re-metering, particularly in flows below 20SLPM or operating at low pressures. One solution uses Alicat’s mass flow meters in combination with the Wilke Semi-empirical method for mixed gas […]

    Characterizing a filter with differential pressure

    Filter characterization with differential pressure An Alicat Differential Pressure Controller is used to characterize a filter’s flow vs. a pressure drop curve. The PC-15PSID-D pressure controller is used to set the pressure drop across the filter. The M-10SLPM-D mass flow meter is used to measure the flow rate required to generate that pressure drop. As […]

    Using mass flow rate to replace pin gauge testing

    Using mass flow rate to replace pin gauge testing Companies continually seek ways to cut costs and improve cycle times. Alicat routinely receives inquiries from customers looking to leverage our technology to accomplish those goals. A customer recently contacted us hoping to improve the speed and reliability of his go/no-go test. The test required that […]

    In-house check of gas chromatograph operation using a portable flow meter

    In-house check of gas chromatograph operation Gas chromatographs (GCs) detect materials at molecular level by preparing a sample of the material that is “carried” on a gas stream into the GC. The carrier gas flow stream is sent into small capillary flow tubes and then into detectors to sense and quantify the suspected materials. These […]

    Flow meters for calibrating air canister sampling flow controllers

    Calibration of flow controllers for air canister sampling Canisters built for air sampling draw air into them using vacuum and passive flow control. With no more of a user interface than a simple screw adjustment, the integrated flow controllers require connection to a volumetric flow meter to establish their test flow rates. The challenge in […]
