- Atomic weight
- The atomic weight of N is 14.0067, of H — hydrogen — is 1.00794 and of O — oxygen — 15.9994.
- The ratio between the AN content and the N content, which depends on the atomic weight of the elements, is 2.86.
- The ratio between the AN content and the N content, which depends on the atomic weight of the elements, is 2.86. Consequently, since the product concerned contains more than 28 % by weight of N, it automatically contains more that 80 % by weight of AN (normally between 94 % and 97 %) [8].
- Although the operational requirements of different SEMs may vary, generally to obtain the best visibility and resolution, with relatively low atomic weight materials, accelerating voltages of 5-10 keV should be used with a small spot size setting and short working distance.
- Although the operational requirements of different SEMs may vary, generally to obtain the best visibility and resolution, with relatively low atomic weight materials, accelerating voltages of 5-10 keV should be used with a small spot size setting and short working distance. As a linear traverse is being conducted, then a 0° tilt should be used to minimise re-focussing or, if the SEM has a eucentric stage, the eucentric working distance should be used.
