SO4-S.

This is a soil salinity test. This method determines the amount of sulfur in a saturated paste extract using Inductively Coupled Plasma Emission Spectrometry (ICP-AES). Sulfur results are assuming that all sulfur present is in the sulfate from. The method has a detection limit of 0.1mg/L.

SO4-S.

This is a soil fertility test. This method estimates the amount of sulfate sulfur in the soil by extraction with monocalcium phosphate. This method is only accurate for the time of sampling since sulfur is constantly being mineralized in the soil. The method has a detection limit of approximately 0.5 mg/kg sulfur as sulfate and is generally reproducible within 8%.

S. This test method determines the concentration of sulfur by utilizing an acid digestion and determination by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The method has detection limits ranging from 0.1 mg/Kg. The method is generally reproducible within 8%.

Total C. This method quantitatively determines the amount of total carbon and inorganic carbon in liquid samples.  The method has a detection limit of 0.5 mg/L.

TDS. This method quantifies solids in water or wastewater samples using gravimetric analysis following oven drying.   Solids refer to matter suspended or dissolved in the water or wastewater and may affect water or effluent quality in adverse ways. Waters with high dissolved solids generally are of inferior palatability and may induce unfavorable physiological reactions in transient consumers. Solids analyses are important in the control of biological and physical wastewater treatment processes and for assessing compliance with regulatory agency limitations. The method has a detection limit of approximately 4 mg/L for TSS and 10 mg/L for TDS, TS and VSS. The results are generally reproducible within 10%.

Total N. This method quantitatively determines the amount of nitrogen in water based on the wet oxidation of organic matter using sulfuric acid and digestion catalyst and conversion of nitrogen to ammonium. The method is used to assess nitrogen content. The method detection limit is approximately 0.5 mg/L and is generally reproducible within ± 10%.

N, C.

This is a soil fertility test. This method determines the total amount of all forms of nitrogen and carbon in the soil. The analytical method is based on the combustion which converts all components into combustion gases which can be measured. The method has a detection limit of approximately 0.02% for carbon and nitrogen.

TOC.

This is a soil fertility test. It determines the total amount of organic carbon in a soil sample. This analysis is based on Shimadzu C/N analyzer for solid samples.

TS. This method quantifies solids in water or wastewater samples using gravimetric analysis following oven drying. Solids refer to matter suspended or dissolved in the water or wastewater and may affect water or effluent quality in adverse ways. The method has a detection limit of approximately 4 mg/L for TSS and 10 mg/L for TDS, TS and VSS. The results are generally reproducible within 10%.
