liquid chromatography, LC), 기체인 경우 기체 크로마토그래피(gas chromatography, GC)로 분류한다.
가장 일반적으로 크로마토그래피를 분류하는 방법은 샘플(solute)과 고정상 간의 상호작용 메커니즘에 기초하고(Fig.1.에서 보여준다.), 그 종류는 다음과 같다.
(1) 흡착 크로마토그래피(Adsorption chromatography)
고정상
1. Typical composition of wood (biomass) and coal.
(2) Liquid and gas fuels
Most
liquid

are
a

hydrocarbons.
For

hydrocarbons, with many others present in very small quantities.
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

1. HPLC (High Performance[Pressure] Liquid Chromatography)란 무엇인가?
이동상에 액체를 쓰는 액체 크로마토그래프의 일종으로 고압 LC(high pressure LC), 고성능 LC 등으로 말하는 경우도 있다. 보통 HPLC로 불리며 액-액, 액-고, 이온교환, 겔 침투 크로마토그래피 4종류로 분류
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
