Analysis was conducted in electron
ionization mode using a GC×GC/ToF-MS Pegasus 4D (LECO, St. Joseph,
MI) equipped with an Agilent 7890B gas chromatograph (Palo Alto, CA).
The columns used were the DB-1 MS UI (25 m × 0.25 mm × 0.25
μm; Agilent Technologies) and Rxi-17 Sil MS column (1.2 m ×
0.25 mm × 0.25 μm; Restek) in the first and second dimension,
respectively (Table S3).

Quantifying Iopamidol and Its Transformation Products

Check if the same lab product or an alternative is used in the 5 most similar protocols

Iopamidol was quantified by using a hybrid quadrupole-orbitrap mass spectrometer (Q Exactive, Thermo Fisher Scientific Inc., Waltham, MA, USA) coupled with liquid chromatography (UltiMate 3000 LC systems, Thermo Fischer Scientific Inc.). To investigate the TPs derived from the iopamidol-containing solution during ozonation and ozonation-chlorination, their accurate masses were similarly determined by using the hybrid quadrupole-orbitrap mass spectrometer coupled with liquid chromatography. Two low-molecular-weight iodic TPs (iodoacetic acid and iodoform) were quantified by using the LC-MS/MS system (LC, UltiMate 3000 LC systems; MS/MS, Q Exactive, Thermo Fisher Scientific Inc.) and a GC-MS system (QP2010 Plus, Shimadzu Corporation, Kyoto, Japan) equipped with a capillary column (DB-1ms UI, Agilent Technologies, Palo Alto, CA, USA; length, 30 m; internal diameter, 0.25 mm; thickness, 0.25 µm), respectively. Details regarding measurements are described in Supplementary content.

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.
