Which of the statements regarding two-dimensional gas chromatography are TRUE? I Two-dimensional gas chromatography is often called GC GC II. Two-dimensional gas chromatography uses two columns that have the same retention selectivity but different lengths to resolve component of complex samples. III. The modulator positioned between the two columns accumulates eluate from the first column in a very short period of time and then rapidly admits the accumulated eluate onto the second column IV. The first column should be shorter than the second column so as to obtain a rapid separation in the second column V. For high resolution, the second column is narrower than the first column and has a thinner film of stationary phase than the first column O I, II, III, and V O II, III, IV, and V O II, V, III, I, IV OI, III, and V O I, III, IV, and V
