To determine the content of selected macroelements and heavy metals on the stands of F. vulgaris, mixed soil samples were taken from two habitats: a variable-wet Molinia meadow with hydrogenic soil and a xerothermic grassland with calcareous rendzina. From the top layer of the soil profile (5–20 cm), the soil samples were collected at 10 points and then mixed to obtain a general sample. Five general samples were taken for each stand. Soil samples were dried and sieved with 2 mm sieve. For both stands, soil reaction (pH in KCl) and assimilable forms of macro- and microelements were examined using the Mehlich-3 method [34 (link)], by means of inductively coupled plasma optical emission spectrometry with Avio 200 ICP Optical Emission Spectrometer (PerkinElmer Inc.). This method is based on calorimetry and flame photometry of the content of elements [35 (link)]. It is the standard method used in agricultural soil monitoring, it allows to test in one soil extract the content of basic macronutrients, such as P, K, and Mg, but also other important nutrients-S, Ca or micronutrients, e.g., B and Cu [36 (link)]. NO3-N was extracted by shaking in H2O (in 1:5, w:v) and measured with Laquatwin Nitrate Ion meter (Horiba co.) according to factory protocol.
Avio 200 icp optical emission spectrometer
Manufactured by PerkinElmer
The Avio 200 ICP Optical Emission Spectrometer is a laboratory instrument designed for elemental analysis. It utilizes inductively coupled plasma (ICP) technology to excite and ionize samples, and optical emission spectrometry to detect and measure the specific wavelengths of light emitted by the excited elements. The Avio 200 is capable of analyzing a wide range of sample types, including liquids, solids, and gases, to determine the elemental composition and concentration of the analytes present.

TGA was used to obtain the proportion of ferritin cage of entire magnetoferritin nanoparticles by using TGA/DSC 3 STARe thermogravimetric analyzer (Mettler Toledo). The desalted and dried samples were heated from 30 °C to 700 °C at 5 °C min−1 under a N2 flow at 50 mL min−1. N2 flow is used to prevent the further oxidation of Fe3O4. ICP-OES (Avio 200 ICP Optical Emission Spectrometer, PerkinElmer) was used to determine the iron content of magnetoferritins. The iron standard sample was diluted into 0 ppm, 20 ppm, 40 ppm, 60 ppm, 80 ppm and 100 ppm, and the samples were dissolved by 5% (v/v %) hydrochloric acid and prepared with the concentration lower than 100 ppm before measured.
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.
