Abstract

ABSTRACT---Sodium,  potassium and calcium  in  standard sample solution  were analyzed with  a portable analyzer  of  liquid  electrode  plasma optical emission spectrometer  (LEP-OES) to assess  its validity for  quantitative  analysis. Reproducibility  and sensitivity  were  investigated  using  different  disposal  sample chip  and applied voltage.  ln  the applied voltage of  800 V, there is no  increasing period  of emission  intensity by  consecutive measuremenl  and  the  relative  standard deviation  among  chips  was  less  than  20%.  The sensitivity  of  emission  intensity  for  Na  and K  were  proportional  to  the  applied  voltage, but  Ca  wasexponential.  The  sensitivity  was  different  by  kinds  of  element  and  applied  voltage.  According  to  its reproducibility,  the spectrometer would  be used  for quantitative  analysis.Permalink : http://ejournal.undip.ac.id/index.php/sm/article/view/3115

Abstract

Symptoms of Diabetes Mellitus (DM) or diabetes could be indicated by measuring blood sugar levels in the body. One of the health technology to detect blood sugar in non-invasive is to utilize the absorption of laser light and oxymeter sensor capable of generating a voltage change on a variety of fluid medium. This study has been designed using the blood sugar measuring device microcontroller ATMega 8535 as a minimum system in controlling the value of output in the form of data digital. System/equipment to be fabricated in this study is a non-invasive method (without injuring the patient's body when taking a blood sample) to determine the blood sugar content by exploiting the physical properties of absorption of laser sensors on a variety of blood sugar content. To improve the quality of the test data used 8-bit microcontroller that is capable of separating the output data 256 bits (binary). Each of these bit values can be used to replace manual sensor test results that have analogue voltage output of the data. This analogue data will then be converted to analogue to digital converter (ADC) into digital values are displayed in the liquid crystal display (LCD) that is directly readable by the measured/patients in a short period of time less than 5 minutes. The results of the research can be developed into a national program providing portable medical test equipment is cheap and movable.
