Clinical chemistry auto-analyzer ADVIA 2400 Chemistry System, provided by Siemens, Munich, Germany, with 2400 test/h capacity and two reagent trays (R1 and R2). Mettler MS204S balance. pH-meter pH-211 Hanna Instruments equipped with a Porotrode pH glass electrode by Metrohm, Herisau, Switzerland was also employed.
Porotrode ph glass electrode
Manufactured by Metrohm
Sourced in Switzerland, Italy
The Porotrode pH glass electrode is a type of pH electrode used for pH measurement in laboratory applications. It features a porous glass diaphragm that allows the sample solution to come into contact with the reference electrolyte, enabling pH detection. The Porotrode electrode is designed to provide stable and reliable pH measurements in a variety of laboratory settings.

A clinical chemistry auto-analyzer ADVIA 2400 Chemistry System, provided by Siemens (Munich, Germany), with 2400 test/h capacity and two reagent trays, was used in the present study.
Visible photometric determinations of thiols and of the redox factors involved in the speciation of the TAC were carried out using a V-550 spectrophotometer provided by Jasco (Cremella, LC, Italy), with a cuvette optical path length of 10 mm.
The determinations of both lipid-soluble antioxidants and L-ascorbic acid were carried out using the Hewlett-Packard 1100 UV HPLC System, provided by Agilent (Santa Clara, CA, USA), including the HP G1322A vacuum degasser, HP G1310A isocratic pump, HP G1313A autosampler, HP G1326A thermo-stated column compartment, and HP G1314A UV-VIS detector.
A pH meter pH-211 Hanna Instruments (Ronchi di Villafranca Padovana, PD, Italy) equipped with a Porotrode pH glass electrode by Metrohm (Origgio, VA, Italy) was also used.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
