Article Abstract
Background: The ADAMS™ HA-8180V is the 8th generation of a fully automated ion-exchange HPLC system from ARKRAY, and the first to be released onto the US market. We evaluated the HA-8180V, for routine hemoglobin A1c measurement in comparison with the Roche Cobas c501, the Tosoh G8 analyzer for normal hemoglobin, and with the Trinity analyzer for hemoglobin variants.
Methods: The analytical performance (linearity, precision, carryover, and sample stability) was assessed based on the Clinical and Laboratory Standards Institute (CLSI) and manufacturer guidelines. A comparison of the HA-8180V against two major analytical methods was performed for 100 whole blood samples. HA-8180V variant mode was also compared against the Trinity ultra2 A1c analyzer for 50 samples containing hemoglobin variants (HbC 14, HbS 14, HbD 12, and HbE 10).
Results: The within-run and total CVs were <0.01 and 0.75% at low HbA1c concentration and 0.46 and 0.63% at high HbA1c concentration, respectively. Linearity was shown in the concentration range 3.4-18.1% HbA1c, carryover was 0.00%, and stability values were excellent. Method comparison demonstrated a high concordance between methods.
Conclusion: The eighth generation ADAMS HA-8180V A1c analyzer demonstrated high analytical performance adequate for routine clinical use.

Phytate in plants (inositol phosphates, InsPs) affects mineral bioavailability. However, methods for their quantification may lead to variable results, and some are nonspecific (spectrophotometric techniques). In this study, ion-pair high-performance liquid chromatography (HPLC) was coupled with post-column derivatization to allow fluorescence detection (FLD, λ324/λ364 nm) of InsPs.

Carbohydrates are essential biomolecules that play a vital role in various biological processes across humans, plants, and bacteria. Despite their ubiquity, the structural elucidation of carbohydrates, particularly oligo- and polysaccharides, remains a significant challenge due to their complex and heterogeneous nature. The high-performance anion exchange chromatography (HPAEC) or called ion chromatography (IC) coupled with pulsed amperometric detection (PAD) has emerged as a powerful tool for highly effective separation and highly specific detection of glycans.

Objectives: To describe a variant hemoglobin that interferes with HbA analysis by cation exchange HPLC.
Case Presentation: A 78 years-old Spanish male patient visited the Internal Medicine Clinic for a routine check-up, with HbA included to screen for diabetes. He had suffered hypertension and dyslipidemia, and the patient had no previous symptoms suggestive of diabetes such as hyperglycemia, weight loss, polydipsia, polyuria or tiredness.
