　　【中国化工仪器网技术前沿】光谱仪器是对物质的成分和含量进行定性和定量分析的光学式分析仪器。它在在冶金、地质、化工、医药、海洋、环境保护、半导体、生物医学、航天探测和同位素应用等许多领域中都是发挥重要作用。随着国内外科技水平日新月异，在光谱技术研究领域取得了诸多突破性进展。近期，在我国科研仪器领域，国内外新型光谱仪相继涌现，为各领域分析检测提供支撑。

　　美科学家发明新型电磁诱导透明光谱仪

　　近日，美国国家标准技术研究院(NIST)发布消息称，其科学家发明了新型电磁诱导透明(EIT)光谱仪。该光谱仪可以高精度地测量单光子源的特性，使未来通信网络不易受黑客攻击成为可能。同时，该设备可以集合其它工艺，将EIT新型光谱仪的性能扩展到任何其它波长范围，且不影响光谱分辨力、高波长精度和高检测灵敏度，将为夜间构建有效量子中继器提供可靠的工具。

　　我国成功研制新型X射线荧光光谱仪破依赖进口格局

　　1月10日，北京安科慧生科技有限公司对外发布，由该公司科技人员经过三年的科研攻关，自主研发成功的新型X射线荧光光谱PHECDA-MINI，将成为解决污染场地污染物快速筛查和污染事故应急监测的关键突破口。其不仅可以大幅减少工作量，还能降低监测成本。这项技术的研发成功，将X射线荧光应用领域扩展到食品安全、环境保护等行业，改变了传统的分析手段，提升实验室分析能力。

　　美国研究人员研发出用于行星探索的紧凑型光谱仪

　　12月21日来自美国弗吉尼亚州汉普顿的消息称，一种用于行星探索的紧凑型光谱仪器已经开发出来。该系统被称为定位超小微型拉曼(SUCR)仪，能够以10微米的分辨率在几厘米(2-20厘米)范围内检测和鉴定矿物质、有机物和生物材料。该主动遥感系统由一个532纳米激光器和一个微型光谱仪构成。未来可用于生物医学、食品分析以及其他无需将样品送至实验室即可从快速化学分析中受益的应用。

　　IBM可探测甲烷的硅光子光谱仪问世

　　据麦姆斯咨询报道，IBM研究人员已研制出吸收光谱平台，可以扩展到红外光谱“指纹区”。IBM公司Thomas J. Watson研究中心的团队展示了一种基于硅光子技术的芯片级光谱仪，对甲烷的探测灵敏度达100ppm。该平台采用光纤连接1650 nm半导体激光器和砷化镓铟(InGaAs)近红外探测器来探测甲烷浓度，并使用可调谐二极管激光吸收光谱技术(TDLAS)。这种方式为未来用于气体泄漏检测和废气偷排监测等应用提供低成本、高灵敏度的甲烷探测器解决方案。

　　中科院化学所国家重点实验室成功研制新型光谱仪

　　近，中国科学院化学研究所分子反应动力学国家重点实验室在国家自然科学基金委重大仪器研制项目的支持下，成功研制了具有亚波数分辨(<1cm-1)的界面和频振动光谱系统。其飞秒红外脉冲的半高宽大于250波数，可一次性覆盖400波数以上的红外区间，光谱分辨率达到0.4个波数，优于上已报道的同类型设备参数，比传统飞秒宽带和频光谱10-20波数的光谱分辨率有极大的提高。该仪器可用于测量气液界面、气固界面、超分子手性界面、生物膜界面的分子振动光谱、分子取向结构和动力学。

　　纵观我国科学仪器发展现状及未来趋势，便携式、小型化、高精度科学仪器已经成为行业发展的一大趋势。而随着国内科学技术不断进步，目前新型的仪器设备正在加速研发，适应市场需求。光谱仪作为分析仪器的一类，在食品、医疗、生物等各个分析检测领域都有着较为广泛的需求，行业发展前景明朗。

　　就我国光谱仪器领域而言，在科研技术和国家创新政策鼓励下，为我国科研仪器研发提供了良好的市场契机。未来，紧随行业趋势，创新技术研发，满足市场需求，是我国光谱仪器行业发展必走的一条道路！
