These carbon pools, sometimes referred to as POC, HOC and ROC, respectively, can be used as inputs into carbon accounting applications such as the Roth-C model. This study examines whether ramped thermal oxidation, combined with evolved gas (CO₂) analysis (RTO-EGA) of soil samples at temperature intervals between 110 °C and 1000 °C, can quantify the allocation of SOC to these pools. RTO-EGA ramping profiles of 176 samples were combined with respective soil carbon pool data obtained from physical fractionation and ¹³C NMR analysis, into multiple linear regression (MLR) and partial least squares regression (PLSR) models. The samples were split into calibration (110) and validation (51) sets for modelling, and 15 samples omitted due to excessively low decomposition temperatures and associated high model leverage. The samples were also modelled by PLSR using mid-infrared diffuse reflectance (DRIFT) for comparison with RTO-EGA. RTO-EGA and DRIFT calibration and validation accuracies were generally high for POC and HOC, with R² values of 0.80-0.95 and RMSE values of 0.10-0.20 %C. Estimates of the ROC pool were relatively less accurate for samples not adequately covered by the calibration set. Since high-temperature carbon analysers are routinely used in most soil testing laboratories, the RTO-EGA approach can be easily adopted for carbon pool analysis. This proof-of-concept study demonstrated that the RTO-EGA method, combined with chemometric modelling, as a rapid and cost-effective method to quantify carbon pools.</p>","PeriodicalId":435,"journal":{"name":"Talanta","volume":"295 ","pages":"128358"},"PeriodicalIF":6.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is an urgent need to develop a simple and economical cell-counting platform for T lymphocyte subsets to meet clinical needs of cancer prognosis. Based on the vertical flow assay (VFA) and a polystyrene (PS) microsphere-labeled antibody specifically binding to target cells, we established a simple T lymphocyte counting assay (PS-VFA). Labeled cells induced a signal, which was detected on the filter membrane. We used 3D printing to create a cell phone holder and a test kits. The cell phone holder eliminates ambient light interference and provides the appropriate focus, and a smartphone was used for image acquisition and data analysis, revealing the number of T lymphocytes to be tested via RGB signal analysis. The entire detection process takes about 15 min, and the detection device is extremely cheap, about $20, and can be reused. CD3, CD4, and CD8 cells count exhibited a quasilinear response to logarithmic cell concentrations in a single nucleated cell solution, and detection limits ranging from 100 to 1400 cells/μL for CD3(R² = 0.96), 100 to 1400 cells/μL for CD4(R² = 0.97), and 25 to 800 cells/μL for CD8(R² = 0.96), respectively.
