Two-dimensional fluorescence analyzer(LH-EDYG)

1)Product principle

LH series of fluorescence analyzers can be applied to detect fluorescent material in multi-field. In the field of geological exploration, it is the on-site technique to analyze fluorescence spectrum of drilling cores, cuttings, sidewall coring and drilling fluid quantificationally. By using fluorescence property of crude oil and measuring spectrum of sample, parameters such as oil concentration, series level and oily index can be gotten. The software has the function of spectrogram identification, which can remove the drilling fluid's pollution intelligently. The analyzers can be applied on-site to discover oil and gas show timely, distinguish true or false show accurately, interpret and evaluate oil reservoir rapidly, particularly the light oil reservoir.

LH-EDYG is researched by L&O and professional optical company from Netherlands. It contains high sensitivity optical path and SNR circuit. The Innovative fiber optical system makes the volume of LH-EDYG small and portable.

2)Main technical parameters

◎Light source：Low - tension cold lamp

◎Excitation wavelength：254 nm

◎Emission wavelength：200-600 nm

◎Accuracy of wavelength：±1 nm

◎Repeatability of wavelength：±1 nm

◎Cuvette：Fluorescent quartz type, with sealed protective shell

◎Sensitivity：0.1 mg/L

◎Cycle time of analysis：20 s

◎Size：355×325×120 mm

◎Weight：6.5 kg

3)Technical advantages

★ Small size, light weight, convenient carrying, suitable for logging site and offshore platform.

★ No need of preheating after power on, sample analysis cycle is very short: 20 seconds for 2-D; 30 seconds for 3-D.

★ The cold light source is low-tension, which can run for long hours continuously. Its service life is up to 3000-5000 hours.

★ Cooled CCD Optical detector can receive and analyze full wavelength range of oil fluorescence, discover and distinguish light oil reservoir effectively.

★ The optical fiber transmission system can reduce noise, improve the SNR and make the analyzer easy to be maintained.

★ The quartz cuvette with sealed protective shell can prevent the sample from volatilizing and improve the repeatability.

★ The intelligent software system is of powerful function, which contains gathering, analysis, interpretation, report forms, print, etc. By the unique function of spectrogram identification, the software can eliminate the interference of drilling additives or mixed oil, which helps us distinguish true or false oil shows accurately.
