Matrix interference could include compounds directly affecting instrument sensitivity. It could also be target or non-target compounds masking the signal of those being targeted. High concentrations of target analytes could also be a cause for dilution. Heavily coloured extracts could also be cause for interference.
Dilution of the sample matrix is the primary approach to combat or decrease the impact of interferences and are the typical cause for raised RDLs.
A dilution directly affects the RDL or detection limit by the same magnitude . e.g. if a 5 x dilution was performed, the RDL is also raised by a factor of 5.
The dilution ensure instrument functionality and confidence in the reported data.
