Laser-induced fluorescence detector (LIFD) is one of the most sensitive detection methods in analytical chemical files.And it was widely used in many fields, such as environment, life science, food science and drug analysis.Confocal optical configuration is widely used in LIFDs.For this LIFD, the effective approaches to achieve the best sensitivity are improving the collection efficiency of fluorescent signal and minimizing the background noise.We have reported a new LIFD for HPLC, using a novel Z-type reflective flow cell to improve the collection efficiency of fluorescent signal.Base on it, a novel three-diametional adjustable confocal laser-induced fluorescence detector was developed, using a new three-dimetional adjustable support of reflector to improve the coaxial precision and modularized optical system to minimize the background noise.

面对惊人的住房价格，个人合作建房正在全国各地风起云涌。 2003年，北京有人提出个人合作建房的设想。进入2005年后，此类方案在广州、沈阳、深圳、南京、厦门、武汉、杭州、成都等城市纷纷出炉。2006年底，“个人合作建房”再次在温州“破冰”。“二次革命”的汹涌来势，让想买房而又囊中羞涩的普通百姓充满了期待。个人合作建房的春天是否真的要到来了？ 遍地开花的合作建房 温州模式：让人燃起安居
