SPI Supplies Combination Mineral and Metal Standards, 59 Standards, Standard for Microanalysis

Contains 59 inert or otherwise highly stable metals, minerals or compounds, for which compositions and purities are supplied. A convenient-to-use diagram accompanies each mount showing the layout of the standard materials and the relative locations of the set The unique labelling made by electron beam etching techniques makes for easy identification and high through put of samples. This 6 mm high x 25mm diameter mount, based on a stainless steel block construction design comes with a built-in Faraday cup as standard. We are sometimes asked to provide this product without the Faraday cup, our customer thinking that somehow the product could be purchased at a lower cost. Actually, since the product is made in production quantities, for us to make one special, without the Faraday cup, the cost for us would in fact be higher. We will always do what the customer asks, but unless an order for ten or more is being placed, such as from an OEM manufacturer.
