We evaluated the performance of the i-STAT Portable Clinical Analyzer, a hand-held
instrument that, with its current cartridge, analyzes for electrolytes, urea nitrogen, glucose …

We measured the emf of NaCl solutions (120-160 mmol/L) with a home-built cell in steady-
state and with some commercial direct potentiometric analyzers about 20 s after the sample …

We measured the emf of NaCl solutions (120-160 mmol/L), with and without the addition of
KCl (5-20 mmol/L), CaCl2 (2-8 mmol/L), or MgCl2 (1-4 mmol/L). Measurements were made …

BACKGROUND: Measurements of free (ionized) calcium (iCa) are increasingly requested in
patient care locations where immediate analysis is unavailable. Evacuated blood collection …

Biomedical, Newton, MA) ion-selective electrode type of analyzer relative to that obtained
with flame photometry. They were concerned because their results were in disagreement …

We evaluated the analytical performance of 10 representative channels on the new
microprocessor-controlled DuPont aca III according to the guidelines (draft documents PSEP …

Background: Lipemia affects electrolyte concentration obtained by indirect ion selective
electrode (ISE) method, but the specific influence on measurements by direct ion selective …

Objectives To determine an optimal specimen type to be used for measurements of ionized
calcium (iCa) so that it applies properly to the reference interval. Also to determine the …

Objectives: The present study was conducted with the aim to compare the sodium (Na) and
potassium (K) results on arterial blood gas (ABG) and electrolyte analyzers both of which …

Background Anion gap (AG) aids the differential diagnosis of acid-base disorders. Its value
has decreased, because of new analytical methods. Our goal was to compare AG reference …
