14个传感器的iNose电子鼻在饮料方面的应用 |
上海瑞玢国际贸易有限公司同您分享14个传感器的iNose电子鼻在饮料方面的应用4则。更多资讯欢迎关注微信公众号:isenso17。
1. 图1 糯米香茶茶汤的PCA图
14个传感器的iNose电子鼻系统对不同干燥方式的糯米香茶茶汤风味进行分析检测:14个传感器的iNose电子鼻对恒温鼓风干燥、真空干燥和真空冷冻干燥的糯米香茶茶汤3种不同干燥方式糯米香茶茶汤区分能力较强。
2. 图2 不同等级信阳毛尖茶的PCA图
Smartongue智鼻在有机茶香气成分的对比研究中的应用:特级茶叶和一级茶叶之间有很明显的界限,即利用14个传感器的iNose电子鼻技术结合PCA识别方法可以区分信阳毛尖特级茶和一级茶。
3. 图3 不同红茶主成分分析图
14个传感器的iNose电子鼻技术在海南红碎茶中的应用:不同红茶用14个传感器的iNose电子鼻技术均可呈现不同的香气指纹图谱,可以区分不同的茶叶,其中碎1(春)、 碎3(春)和碎5 (秋)在第二象限内,碎2(春)、 碎4(春)和碎 5(春)在第三象限内,而且比较紧凑,碎3(秋)、碎4(秋)、 碎1(秋)和中瑞CTC红茶均分布在第一、四象限内。
4. 图4 三种样品的PCA分析图
可乐饮料的iNose电子鼻利用14个传感器的检测研究:样品未经处理时,三类样品的数据点分布均比较离散,且各类样品相互重叠难以区分。样品经碳酸钠干燥处理后,三类样品的数据点分布比较集中,且相互分离易于区分。

NanoBrook产品应用-12-ZetaPALS
文献名: Structural, morphological and optical properties of Bi NPs obtained by laser ablation and their selective detection of L-cysteine 作者: Ramon Gabriel Teixeira Rosaa, Celso de Araujo Duartea , Wido Herwig Schreinera, Ney Pereira Mattoso Filhoa, Arandi Ginane Bezerra Jr.b, Andersson Barisonc, Fernanda Maria Marins Ocamposc a Departamento de Física, Universidade Federal do Paraná Centro Politécnico, CP 19044, 81531-990 Curitiba (PR), Brazil b Departamento Acadêmico de Física, Universidade Tecnológica Federal do Paraná, 80230-901 Curitiba (PR), Brazil c Departamento de Química, Universidade Federal do Paraná Centro Politécnico, CP 19081, 81531-990 Curitiba (PR), Brazil 摘要:In the present work we show the results of the investigation of the properties of bismuth nanoparticles (NPs) obtained by the laser ablation in water. The samples were characterized by various techniques: UV/vis spectroscopy, dynamic light scattering, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear magnetic resonance and zeta potential. The NPs were metallic and surface oxidated, exhibiting absorption peak at 257 nm due to the surface plasmon resonance. The interaction between the NPs and various amino acids was studied and revealed a selective sensibility to cysteine on a range of concentration from 80 to 720 μM, which we attribute to a dimerization of cysteine to cystine probably complexed to the nanoparticle surface by electrostatic interactions, leading to the modification of the NP absorption spectrum. 关键词:Bismuth; Nanoparticles; Laser ablation; Cysteine

双相不锈钢的增强纳米压痕应用
Using Bruker’s Hysitron PI 88 SEM PicoIndenter equipped with tilt and rotation stages in conjunction with the QUANTAX EBSD system enables a more robust characterization of metallic materials by combining high resolution phase and grain orientation mapping capabilities with targeted nanomechanical property measurements. This combination could also be used to extend the scope of research related to other advanced textured, anisotropic, or multi-phase materials.
