Plant Analytical Tests

This package determines the quantities of zinc, manganese, iron and copper. Zn, Mn, Fe, Cu.

This test determines the dry matter in a compost or manure sample. Partial DM (dried at 55°C).

This method determines the concentration of phosphate-phosphorus in botanical materials. It is determined spectrophotometrically. The method detection limit is approximately 10 mg/kg (sample dry basis) and is generally reproducible to within ± 10.0%. PO4-P.

This method quantitatively determines the concentration of potassium in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.02%. K.

This method quantitatively determines the concentration of selenium in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.02%. Se.

This method quantitatively determines the concentration of sodium in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.02%. Na.

This method quantitatively determines the concentration of sulfur in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.02%. S.

This method quantitatively determines the concentration of vanadium in botanical materials utilizing a nitric-perchloric acid digestion. Digest analyte concentrations are determined by atomic absorption spectrometry (AAS) and/or inductively coupled plasma atomic emission spectrometry (ICP-AES). The method detection limit is approximately 0.5 mg/kg. V.
