"Chemiluminescence Methods (present And Future)"
Grasas Aceites 2002 Volume 53, Issue 1 Pages 64-75
A.M. Jiménez y M.J. Navas

Abstract: This article provides a general review of chemiluminescent methods in some of their recent applications in drug analysis, sea water analysis or antioxidant activity of natural and synthetic products (including olive oil). Practical considerations are not included in the review since the main interest is to state, through the aforementioned applications, that chemiluminescence has been, is, and will be a versatile tool for Analytical Chemistry in future years.

"Direct Olive Oil Analysis"
Grasas Aceites 2002 Volume 53, Issue 1 Pages 1-7
M. Valcárcel, M. Gallego, S. Cárdenas and F. Peña

Abstract: The practical impact of direct analysis is undeniable as it strong contributes to enhance the so-called productive analytical features such as expeditiousness, reduction of costs and minimisation of risks for the analysts and environment. The main objective is to establish a reliable bypass to the conventional preliminary operations of the analytical process. This paper offers a systematic approach in this context and emphasises the great field of action of direct methodologies in the routine analysis of olive oil. Two main types of methodologies are considered. On the one hand, the direct determination of volatile components is systematically considered. On the other hand, simple procedures to automatically implement the preliminary operations of the oil analysis using simple devices in which the sample is directly introduced with/without a simple dilution are present and discussed.

"Automation Of Techniques For Oils Analysis. Determination Of UV Absorbance By Flow Injection Analysis"
Grasas Aceites 1990 Volume 41, Issue 6 Pages 418-422
Garcia Mesa, J.A.;Uceda Ojeda, M.;Luque De Castro, M.D.;Valcarcel, M.

Abstract: A method is described, using a flow injection system (illustrated), for the individual and simultaneous measurement of the absorbance of oils at 270 and 232 nm. Sampling rates are 60 and 20 h-1 for individual and simultaneous measurement, respectively; coefficient of variation are 1 to 2.5%. The method was applied in the determination of the absorbance of olive oil.
