Glutamate concentration can be determined in the following ranges.

• GLU2B: 0.015 - 1.50 g/L (0.1 - 10 mmol/L)
• GLU2D: 0.15 - 15.0 g/L (1.0 - 100 mmol/L),up to 150 g/L (1 mol/L) with postdilution

 
Conversion Factors
Conversion factors for analyte concentration:

• 1 g/L = 6.797 mmol/L
• 1 mmol/L = 147.1 mg/L

Traceability
This method has been standardized against Glutamate net weight.
 
Precision
Representative performance data on the Cedex Bio Analyzer are shown. Results obtained in individual laboratories may differ.
Precision was determined in samples of three concentration levels. Coefficients of variation (CV) were calculated for in-run precision (n=21) and inter-run precision (on 10 days).

	Level 1		Level 2	Level 3
Mean	0.60mmol/L       (88.3 mg/L)		3.51 mmol/L        (516.3 mg/L)	6.99 mmol/L     (1 028 mg/L)
CV in-run	0.8%		0.8%	2.6%
CV inter-run	1.2%		2.2%	2.2%

GLU2B is the standard protocol for glutamate determination. If the glutamate concentration of a sample is expected to be higher than 1.2 g/L (8.2 mmol/L), then protocol GLU2D should be used (same protocol with pre-set 1:10 sample predilution).
Results higher than the valid measuring range will be flagged, and a rerun with an automatic 1:10 predilution will be recommended by the software.
