neutral  Ilya Razmanov: проблема в том, что при shaving отбирают между циклами как раз не пик, а фронт и хвост, а пик гонят на новый цикл
1 hr
  -> Не вижу противоречия — пик выделяют (отбирают), а фронт и хвост отбрасывают

рециркуляционная хроматография


Explanation:
это рециркуляционная хроматография, а вот shaving на русском не встречал. Идея этого shaving в том, что слишком размытый фронт и хвост обрезают (отбрасывают часть вещества), таким образом обуживая пик. Теперь осталось придумать, как это сказать покороче.
