Insight to Nanoparticle Size Analysis—Novel and Convenient Image Analysis Method Versus Conventional Techniques

Table 3 The efficiency of the different methods is estimated by comparing the time required in each case to achieve the results

Sample	TEM imaging and manual image analysis	Number of analyzed particles	TEM imaging and analysis with Nanoannotator	Number of analyzed particles	SAXS data acquisition and analysis^a
Ag	0.7 min/particle	100	0.2 min/particle	400	~30 min
Fe2O3	–	–	0.9 min/particle	100
Graphite	–	–	–	–

^aThe number of the analyzed particles in SAXS measurements is very large when compared to the image analysis techniques. Also, the time required is highly dependent on the SAXS acquisition time
