description: Este trabajo es parte de un estudio mayor sobre seguimiento de actividades cotidianas de personas mayores a través de QUIDA, sistema tecnológico (sensores) para el cuidado de personas mayores en el hogar. El Excel contiene edad, sexo y los puntajes obtenidos por los participantes en los instrumentos aplicados al inicio (Calidad de vida (EQ-5D-3L), Funcionalidad (Índice de Barthel) y Cognición (MMSE-Abreviado). El estudio fue aprobado en CEC-UNAB (Acta 032_21-07-2023), realizado entre 1/agosto/ 2023 hasta 31/mayo/2024. El reclutamiento se efectuó entre los meses de agosto 2023 a febrero de 2024. Se contactaron a diversos grupos de personas mayores (clubes, asociaciones gremiales, talleres). Todos los participantes recibieron información escrita de la investigación y firmaron el Consentimiento Informado antes de iniciar la investigación. La muestra fue 40 personas con 60 o más años, que vivían solas, con residencia en la zona urbana de la región de Valparaíso (Chile), sin problemas funcionales ni cognitivos.

description: This dataset contains Common Data Format (.cdf) files generated from LC×LC–MS analyses of amino acid standards, blanks, and commercial samples, acquired to support multivariate data analysis (MSROI and MCR-ALS) and quantitative calibration.

The files were converted from Waters .raw data using DataBridge (MassLynx®) and are directly compatible with MSroi tools for MATLAB. The dataset enables full reproducibility of the data processing workflow described in the associated study, including ROI extraction, data augmentation, normalization, and MCR-ALS with area-correlation constraints.

Contents

- Standards (calibration): Five concentration levels of an amino acid standards mixture (0.1–0.5 μmol mL⁻¹), prepared in AcN:H₂O (1:1).

- Blanks: Solvent blanks acquired under identical LC×LC–MS conditions.

- Samples:

* Sample A: Aminoven 10% perfusion solution (three replicates), diluted to fall within the calibration range.

* Sample B: Commercial amino acid supplement tablet extract (three replicates), prepared by acidic dissolution, filtration, and dilution.

Analytical conditions

Technique: Comprehensive two-dimensional liquid chromatography coupled to mass spectrometry (LC×LC–MS).

1st dimension: HILIC separation (BEH HILIC column).

2nd dimension: Reversed-phase separation (BEH Shield C18 column) with 1.5 min modulation.

MS: Triple quadrupole with ESI in positive and negative modes, full scan m/z 80–400.

Purpose of m/z range: To minimize solvent/background noise and focus on analytes of interest.
