Trace Element Analysis in Rocket and Purslane

Al, B, Ca, Fe, K, Mg, Mn, Na, Sr, and Zn content was measured in dry samples by inductively coupled plasma optical emission spectrometry (ICP-OES) after mineralization of the dry samples with an acid microwave-assisted digestion system (MARS 6, CEM Corporation, Matthews, North Carolina) performed as reported by D’Imperio et al. [34 (link)]. To confirm the accuracy of the measurements, certified reference vegetable material (CRM, NIST tomato leaf 1535a) was analyzed using the same procedure as the rocket and purslane samples.

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.
