A study on the development of a compensation method for humidity effect in QCM sensor responses

Mumyakmaz, Bekir; Özmen, Ahmet; Ebeoglu, Mehmet A.; Cihat Tasaltin; Ilke Gurol (ELSEVIER SCIENCE SA, 2010)

In this study, humidity influence on quartz crystal microbalance (QCM) sensor responses during gas applications is investigated. The goal is to search a compensation method to remove humidity influence over the QCM sensor ...
A study on transient and steady state sensor data for identification of individual gas concentrations in their gas mixtures

Gülbağ, Ali; Temurtaş, Feyzullah (ELSEVIER SCIENCE SA, 2007)

In this study, a comparative study was performed for the quantitative identification of individual gas concentrations (trichloroethylene and acetone) in their gas mixtures using transient and steady state sensor responses. ...
Classification of E-Nose Aroma Data of Four Fruit Types by ABC-Based Neural Network

Adak, Muhammed Fatih; Yumuşak, Nejat (MDPI, 2016)

Electronic nose technology is used in many areas, and frequently in the beverage industry for classification and quality-control purposes. In this study, four different aroma data (strawberry, lemon, cherry, and melon) ...
Column solid phase extraction of copper and nickel on triethylenetetramine bonded silica gel for their atomic absorption spectrometric determination

İmamoğlu, Mustafa (TAYLOR & FRANCIS INC, 2008)

A procedure for the preconcentration of Cu(II) and Ni(II) is proposed using a minicolumn filled with silica gel modified by triethylenetetramine. The retained analytes on the modified silica gel were eluted with hydrochloric ...
