The sample (5 mg) was hydrolyzed (6

The sample (5 mg) was hydrolyzed (6 MHCl; 1 mL) in a
nitrogen atmosphere, for 12 h. The solution was filtered
through Whatman No. 1 and reduced in volume to dryness.
The residue was dissolved in a buffer solution (sodium
citrate, pH 2.20) and injected to a post column derivatizer
(Pickering Laboratories), adapted to a cation exchange column
(Na+, 8 lm, 3 mm ID · 250 mm) and a Perkin-Elmer
785 UV/VIS detector (570 nm

Hasil (Bahasa Indonesia) 2:

Sampel (5 mg) dihidrolisis (6 MHCl; 1 mL) dalam
suasana nitrogen, selama 12 jam. Larutan disaring
melalui Whatman No 1 dan mengurangi volume sampai kering.
Residu dilarutkan dalam larutan buffer (natrium
sitrat, pH 2.20) dan disuntikkan ke derivatizer pasca kolom
(Pickering Laboratories), disesuaikan dengan kolom penukar kation
( na +, 8 lm, 3 mm ID · 250 mm) dan Perkin Elmer-
785 UV / VIS detektor (570 nm
