semicolon

One of my colleagues asked me to revise "To investigate the effect of growth time, graphene films were first synthesized using different heating ramp rates; Figure 1a-c shows SEM images of those synthesized at a ramp rate of 500 °C/h." as follows:

"To investigate the effect of growth time, graphene films were first synthesized using different heating ramp rates; Figure 1a-c showing SEM images of those synthesized at a ramp rate of 500 °C/h."

The reason he gave was "Given the use of the semicolon, it is necessary to use the verb form as a gerund (a verb that functions as a noun) to ensure an independent clause (i.e. that the second part of the sentence contains both a verb and a noun). This also creates a structure that is more akin to that used by native English speakers."

How do I explain that he is wrong?

An independent clause must be able to stand alone as a complete sentence. At the very least, that means it has a subject and a verb. If you change the verb to a noun (a gerund does not function as a verb), you no longer have an independent clause. No verb = no independent clause. Further, most native speakers would use a period (two sentences) instead of a semicolon.
