  • What can I use to filter my mobile phase?

    If you are using mobile phase that contains salts or, generally, any components that are weighed out for its preparation, you will need to filter the solution before using with HPLC or UHPLC. The most common type of filtration is membrane microfiltration. We sell an extensive group of products for this and they are discussed very well in a blog ...

  • Predicting the performance of multi-media filters using artificial neural networks

    The impact of flow rate and turbidity on the performance of multi-media filtration has been studied using an artificial neural network (ANN) based model. The ANN model was developed and tested based on experimental data collected from a pilot scale multi-media filter system. Several ANN models were tested, and the best results with the lowest errors were achieved with two hidden layers and ...

  • Overview of the Whole Copper Recycling Chain

    Copper is of good characteristics. It is easily stretched, molded, and shaped; is resistant to corrosion; conducts heat and electricity easily. Therefore, copper is widely used in construction, power generation and transmission, electronic products manufacturing, and the production of industrial machinery and transportation vehicles. At the same time, as a non-renewable resource, copper is also ...

  • Chemical Reporting and 2016 requirements

    The EPA views the laws as a major victory for chemical safety, public health and the environment. The EPA altered the CBI certification statement for 2016 CDR submission, to be consistent with the new laws requirements. In addition the EPA is updating the guidance, instructions, and informational documents to be consistent with the new language. Manufactures and importers are required to give the ...

  • Optimization of operation conditions for domestic sewage treatment using a sequencing batch biofilm filter

    A sequencing batch biofilm filter (SBBF) was applied to treat domestic sewage. The bioreactor consisted of fibrous filler in the upper part and ceramsite filter media in the lower part. The impacts of the most important factors including dissolved oxygen (DO), water temperature and hydraulic retention time (HRT) were evaluated on contaminants removal during the operation of the SBBF. Changes ...

  • Are incineration and landfills the answer to save us from the recycling crisis?

    For plastic recycling, this year hasn’t exactly been one of the best – what is to blame? Oil. Shockingly, it actually costs more to recycle old plastic than it does to make new in many ways. Petroleum prices have fallen so low, as low as 70% below the level in June 2014. This may be great for some – however with it has fallen the cost of Virgin Plastic which is made from ...
