德國耶拿分析儀器股份公司（Analytik Jena AG）成立于1990年，前身為卡爾?蔡司（Carl-Zeiss Jena GmbH）公司的分析儀器部, 今天已成為德國的分析儀器公司之一。公司總部設(shè)在 光學(xué)精密儀器制造 的德國耶拿(Jena)市。目前Analytik Jena在100多個分支機構(gòu)。德國耶拿的宗旨是不斷創(chuàng)新和追求活力，支柱是其久負盛名的分析儀器。2013年德國耶拿加入Endress+Hauser集團，實現(xiàn)了實驗室儀器與過程控制的結(jié)合。

德國耶拿分析儀器股份公司北京代表處成立于2001年，回首十幾年，耶拿公司在中國一直保持著高速發(fā)展的態(tài)勢，已逐步建立了高品質(zhì)的 品牌形象，形成了耶拿中國 嚴謹、勤奮敬業(yè)的團隊文化。“品質(zhì)造就非凡”是耶拿公司的宗旨，耶拿中國在高速發(fā)展的道路上將一如既往地為廣大用戶提供高品質(zhì)的產(chǎn)品和服務(wù)。

耶拿公司的高速PCR技術(shù)正帶領(lǐng)著PCR技術(shù)向更快、更高的方向發(fā)展，2009年耶拿公司收購了歐洲 的PCR儀生廠商德國Biometra公司和 的自動化移液工作站供應(yīng)商德國Cybio公司,2013年4月又收購了的凝膠成像 制造商——美國UVP公司，更是如虎添翼，從樣品制備、核酸提取純化、 PCR和定量PCR、電泳、凝膠成像系統(tǒng)、各類實驗室常規(guī)設(shè)備，以及多種自動化液體處理工作站等，為用戶提供“一站式”的分子生物學(xué) 全套解決方案。

公司目前的主要業(yè)務(wù)是研究、開發(fā)、設(shè)計和生產(chǎn)制造原子吸收分光光度計（AAS）,電感耦合等離子體發(fā)射光譜儀(ICP-OES),電感耦合等離子體質(zhì)譜儀（ICP-MS),總 碳（TOC）/總氮（TN）分析儀， 鹵素化合物（AOX）分析儀，元素（C、S、N、Cl）分析儀和紫外/可見（UV/VIS）分光光度計和科學(xué)儀器等。另外，Analytik Jena不僅生產(chǎn)制造分析儀器而且還提供實驗室的一體化解決方案。

AJ公司的主要產(chǎn)品和服務(wù)包括: 

化學(xué)分析儀器 - 原子吸收分光光度計，連續(xù)光源原子吸收分光光度計，電感耦合等離子體發(fā)射光譜儀，電感耦合等離子體質(zhì)譜儀，總 碳/總氮分析儀，總 鹵分析儀, 元素分析儀, 紫外可見分光光度計, 微波消解系統(tǒng)和測汞儀;
