美國康塔儀器(Quantachrome Instruments)   
康塔(Quantachrome)是著名的當代顆粒技術開創者。三十年來，康塔(Quantachrome)的科學家革新了測量技術并設計了相應的儀器，使得粉體及多孔物質的測量更加精確、精密，更加可靠。這包括：
· 比表面測量
· 吸附/脫附等溫線
· 孔隙度、孔徑分布
· 化學吸附研究
· 粒度分析
· 真實粉體密度
· 壓汞法孔隙度測量
·汞接觸角

康塔公司具有代表性的發明包括：
- 流動法全自動比表面分析儀 ---- Monosorb
- 6站全自動比表面及孔隙度分析儀 ---- Autosorb-6
- 連續掃描全自動壓汞法孔隙度分析儀 ---- PoreMaster系列
- 氣體法全自動真密度測定儀 ---- UPYC 1000

康塔(Quantachrome)的儀器不僅受到科學界的青睞，裝備了哈佛、耶魯、清華等世界各個著名大學，而且已經向全世界的工業實驗室發展，以滿足那里開發和改進新產品的研究與工藝需求。工廠中也依靠QUANTACHROME的顆粒特性技術更精確地鑒別多孔材料，控制質量，或高效率查找生產中問題的根源 通過顆粒技術使產品上一個臺階，在當今工業界已成為一個不爭的事實。

康塔(Quantachrome)被公認為是對樣品權威分析的優秀供應商，它可為實驗室提供全套裝備及完美的粉末技術，及最佳的性能價格比。康塔公司不僅通過了ISO9001及歐洲CE認證，也取得了美國FDA IQ/OQ認證。
