For processing of the labeling product, C-18 cartridges, Phenomenex Strata-X Tubes, 30 mg were used. Sterile filtration was done on 0.22-μm merane filters (Millex GV). For labeling of octreotide derivatives, DOTA- d -Phe 1 -Tyr 3 -conjugated octreotide (DOTATOC) was used.
After extraction, vessel contents were filtered through Whatman no. 1 filter paper and a 0,22 µm merane filter (Millex-GV, Millipore) into a vial for chromatographic analysis. HPLC quantifiion The concentration of shikimic acid was determined using a Aijiren LC 2010 chromatograph equipped with a Class VP 6.0 software, autoinjector, and photodiode array detector using a detection
Each sample was placed in the center of the microwave glass tray. After extraction, each sample was allowed to cool for 5 minutes and then filtered through Whatman filter paper, and 0.22 micrometre merane filter (Millex-GV, Millipore) for

The total solution was vortexed for 2 minutes and then filtered by Millex-GV syringe filter Unit, 0.22 µm pore size polyvinylidene fluoride (PVDF) merane. Finally, 100 µL of clear solution was
This approach was taken after evaluating the desorption efficiency of all 10 analytes using three different syringe filters (Millex-HV, 0.45 µm; Millex-GV, 0.22 µm; and Millex-GP, 0.22 µm). Adsorption of the selected antineoplastic drugs was observed for at least one compound on each evaluated syringe filter, compromising the efficiency of the desorption step.

(Phenomenex), which had been activated in advance by MeOH and equilibrated in distilled water. e tubes were then washed with distilled water, and the adsorbed materials were eluted with mL of MeOH and ltered on a . m lter( mm,Millex-GV,EMDMillipore
FTIR analysis has shown that the apical oxygen, planar and the oxygen in reservoirs layers, modes are observed around 415–524 cm−1, 564–579 cm−1 and 680 cm−1, respectively.
Before HPLC injection, all samples were filtered through a 0.2‐µm syringe filter, and a 20 μl culture supernatant were used for injection (Millex GV; Millipore). Operating conditions were as follows:temperature 60°C, flow rate of 0.6 ml min −1 , isocratic mobile phase 20 mM H 2 SO 4 .
Today, the most common commercially available 68 Ge/ 68 Ga radionuclide generator is based on a TiO 2 solid phase Phenomenex Strata-X Tubes, 30 mg were used. Sterile filtration was done on 0.22-μm merane filters (Millex GV). For labeling ofd-Phe 1 3
