This result utilises Double Pulse LIBS with a inter-pulse delay of 7us. RMSE results reflect using a calibration based on Vanadium - Hexagonal Mesoporous Silica [V-HMS] (impregnated) to analyse both V-HMS (impregnated) and V-HMS (synthesised samples). However, V-HMS synthesised samples have Vanadium in a different form, which is not similar enough for a good result.
