Whilst Florisil is often the method that lab use be aware that it isn’t truly selective for organic matter and can remove TPH from the extract as well, it becomes a matter of judgement as to how much Florisil is used to achieve the removal of organics without capturing the TPH as well.
At the risk of being too blatant an advert for our own product, QED our rapid onsite hydrocarbon analyser utilises UV fluorescent as its detection method, and as a result isn’t affected by organic matter as it does not fluoresce at the same wavelength as true TPH.

Hi Anita
Many labs offer a 'Florisil Clean-up' to achieve this.
