Design Your Own Standard

Using the SPI Supplies Design Your Own Standard (DYOS) Tool, you can build your own standard block using the combined libraries of both the C. M. Taylor Company as well as SPI Supplies.

To build your own microanalysis standards block, follow the steps below. SPI Supplies Off the Shelf standards are readily available if you do not want to design your own block.

To obtain an individual standard or “loose” unmounted standard please see further information in the “Loose Standard” Section below.

 

Design Your Own Standard Block Process

Completely Finished, Ready-to-use Standard
Using this Tool, you will end up with a completely finished, ready-to-use standard, with each chosen item mounted, polished, carbon coated and electron beam labeled. 

STEP 1: Select a mount layout, or a combination of layouts, with enough holes to accommodate your choice. You do not have to fill all the holes, however, there is an additional fee to cover the cost of filling and polishing these holes using an epoxy. Note the carousel layout which is designed to fit around a 1/2" SEM pin mount. Add your chosen layout to the shopping cart.

The available mounts or blocks can be found in the DYOS Available Blocks Section. Add the selected block to your shopping cart.

STEP 2: Add a Faraday Cup as part of the block. This is an optional item, but many users find the ability to check a beam current while on the standards block to be most helpful. Add this item to the shopping cart if desired.

STEP 3: Select Standards: Using Standards for Microanalysis Periodic Table to search for and add the standards you wish to have in your block. 
The Table allows for the ability to search in a number of ways. You can use the table directly to select a specific element on the periodic table and this will bring up all standard that contains that element ranking them in descending order from weight percent. For example, selecting Manganese will provide you with 36 entries with the pure element manganese listed first at 100% while a Trace Element Glass (SRM 612) will have the manganese listed as below 0.01%.

You also have the option of selecting one of the six categories at the top of the page: Pure Elements, Natural Minerals, Synthetic Compounds, Rare Earth, Glasses and NIST SRMs.Each of these will provide a list of standards in alphabetical, or numerical order.

From any of these points, you can further drill down to the individual standards and get further information on composition and source. 

Note that some standards have two or more similar items (Albite, for instance, has two forms). You will be able to determine which form you would like to add to your block.

STEP 4: Adding the Standard to your Shopping cart is straightforward. Be sure to select the “Mounted” version (not the “Loose”). Some of the items in our collection do not take well to mounting and polishing. This is usually because of their water solubility, such as the halides of the alkali metals. We have adopted the policy not accepting these for mounting, however, they can still be obtained in a loose form for you to use as you see fit. Add a number of standards to fill all available slots (or less one if you have a Faraday Cup). 

If you have a specific placement for these elements, please contact us with that information, otherwise, we will best place these standards based on our experience. Once you have added all your standards, you are ready to submit your order.

STEP 5: Confirmation: We will review your order to ensure that there are not potential issues with any standard selection or availability. Order can take several weeks to several months to complete.

 

Loose Standards

You can purchase individual standard items as loose grains for mounting in your own laboratory. You will receive one grain large enough to mount with care, and a data sheet. Be aware, however, that because of scarcity, not all standards are available in the loose form.

Using Standards for Microanalysis Periodic Table to search for and find the loose standard. Follow STEP 3 above for details on using the Table.
When you find the standard of interest, add the “Loose” item to your shopping cart.
