QuantomiX WETSEM®

QuantomiX WETSEM®

SEM is the primary tool for high-resolution imaging – the cornerstone for research into living organisms and our material environment. But because SEM requires that samples be placed in a vacuum, it has not been suitable for examining wet samples. Quasi-S working together with El-Mul (QuantomiX) provide solution to this major impediment to the use of SEM for biomedical research, as well as for many other clinical and industrial applications. Until now, the only means of imaging a wet sample with EM was to freeze or dry it, effectively changing it’s nature in the process. Such sample preparation is also time-consuming, costly, and often introduces artefacts. El-Mul (QuantomiX) WETSEM® – developed with the cooperation of some of the world’s leading life sciences and materials science researchers and labs – dramatically reduces the preparation needs for high-resolution imaging of wet samples, making imaging easier and faster. It also eliminates many of the artefacts that result when preparing wet samples for EM, opening up opportunities for new research methods as well as new processing methodologies in a variety of fields. WETSEM® also uniquely enables imaging of samples that contain oily and volatile materials. Also for the first time, WETSEM® enables micro-analysis using energy dispersive spectrometry (EDS) of wet samples in their native state, a long-awaited capability for many industrial and research labs. More can be discussed with Quasi-S team in understanding the full potential of this technology.

    QX-102 Capsules — For cell biology and liquid samples

    Request for Quotation

     

    The QX-102 Capsules are used for imaging various wet materials and biological samples such as food, cosmetics, oils, paints, particles in solutions, adherent and non-adherent cells, and microorganisms. Materials of various consistencies such as foams, gels, creams and emulsions can be easily viewed using the QX-102 Capsule. The samples can be visualized either directly or by following appropriate contrast enhancement staining or labeling procedures. The capsule serves as a cell culture dish, specifically designed for the SEM. No coating or embedding of the sample are required, enabling electron microscopy imaging with easy sample preparation comparable to light microscopy

    QX-202C Capsules — For in-situ imaging of dynamic hydration processes

    Request for Quotation

     

    QX-202C capsules are used for in-situ SEM imaging of various dynamic hydration processes. They can be used for imaging the hydration process of cement, gypsum and other materials. The unique design of the QX-202C capsules allows extended studies to be performed inside the SEM vacuum chamber - the dynamic process can be followed for up to 24 hours, removing the need for multiple-sample imaging or repetitive venting of the SEM. There is no need for coating, drying or freezing of the samples. Simply place the sample in the capsule, seal it and image. The samples can be visualized directly using a BSE detector.

    The following images show the early stages of gypsum hydration; the growth of needle like crystals can be followed in the sequence of micrographs. Images were taken at 8, 16, 24, and 60 minutes. The formation of a network of gypsum crystals is evident within the first hour of observation.
