Customised Blocks
Although our Universal Standard blocks are extremely comprehensive, M.A.C. are aware that they do not always provide the specialization that some users require. This is why M.A.C. is happy to work directly with you to help to produce a set of standards as unique as the environment in which they are to be used and reflect the requirements which have been identified. We are able to produce/manufacture blocks for all microanalysis instrumentation or customised mounts specially designed and manufactured. Block material can be as specific as the standards which are mounted and we are able to offer blocks in Brass, Aluminium or Stainless Steel. When enquiring about custom built blocks, we would ask that the following information is provided, to help you with the most appropriate solution. 1. Make and model of instrument in which standards are to be used. 2. Specify quantity and standard materials required. 3. Outer diameter of block or individual required. 4. Inner diameter where appropriate. 5. Thickness of block (5mm normally supplied). 6. Material of the block to be used (normally Brass) 7. Whether a Faraday Cup is required. 8. Any limitation of the X and Y- movements of the stage. 9. The Standard Block type number where possible 10. Any additional requirements.
Customised Standards – Single Individual standards are usually supplied as 2, 3 or 5mm diameter brass tube. Although they can be mounted in any size block.
Unmounted standards We are also able to offer unmounted samples/grains of certified materials which are available. Grains are usually 2mm3
in size.
Customised Standards - Multiple Multiple standards mounted in a single block. The numbers of standards mounted are dependent on the dimensions of the block. These range from 10mm – 32mm are usually 5mm thick, although, blocks can be manufactured to your specific requirements.
Auger Standards Auger Blocks are manufactured from AISI 304 austenitic Stainless Steel with standards embedded with woods metal (Bismuth, Lead, Tin and Cadmium Alloy). Up to 50 standards can be set into one of these blocks, however, the actual number achievable will be dependent on the shape and size of the block.
