Solid samples are analyzed on a LECO Tru-Spec CN analyzer (Leco Corp., St. Joseph, MI, USA). The instrument is primarily used to analyze total C and N concentrations in soil and vegetation samples although it has also been used for fertilizer, animal feeds, animal tissue, plant litter, fecal matter, and wastewater effluents.

Organic C concentrations can be determined on samples following acid digestion, or can be calculated by difference following off-line inorganic C analysis. Both analyses can be performed at the facility.

The instrument is a dry combustion type with infrared detection for carbon and thermal conductivity detection for nitrogen. It is computer driven with an interfaced balance and a 30 position auto-sampler, which allows up to 2 hours of unattended operation.

• Difficult Samples [1]: internal (CSU) + $2.00/sample; non-profit + $2.62/sample, commercial + $3.95/sample


Notes:

[1] Difficult samples require an additional charge:

- TOC, TN - liquid: Non-filtered waters or any sample matrix other than water
- Inorganic N, P - liquid: Any sample matrix other than 2M KCl or water; any sample not near neutral pH; colored samples; dirty samples

EcoCore maintains an Alpkem Flow Solution IV Automated wet chemistry system (O.I. Analytical, College Station TX). The instrument features a 270 position random access auto sampler and the ability to use either segmented flow analysis (SFA) or flow injection analysis (FIA). Two auto ranging detector channels allow simultaneous measurement of two ionic species at up to 60 samples per hour.

Currently available chemistries include:

• Ammonium (NH4+) by segmented flow analysis.
• Nitrate + Nitrite (NO3-+NO2 -) by flow injection analysis.
• Nitrite (NO2-) by flow injection analysis.
• Orthophosphate (PO43- ) by segmented flow analysis.

The instrument is principally used for analyzing water samples and soil extracts.
