Firstly, different types of deflection detectors were compared. The experimental results showed that the bi-cell photodiode detector is most sensitive to the deflection signal. Secondly, the effect of the size of the reaction cell on the detection sensitivity was investigated. A small reaction cell gave a stable baseline and small noise in flow injection experiments, and thus gave a high detection sensitivity. Thirdly, the effects of the optical arrangements on the detection sensitivity were investigated. Focusing the probe beam close to the gold film/CCl4 interface enhanced the detection sensitivity. Also, refocusing the deflected probe beam improved the sensitivity. Under the selected experimental conditions, the detection of the neutralization reaction between HCl and NaOH at sub-nanomol level became possible. Further improvements are also discussed. 26 References', 'language' => 'English', 'updated' => '2020-12-28 11:25:15', 'sjccheck' => 'Yes', 'sjccheckdate' => '2006-07-07 02:11:38', 'hits' => '2', 'urlcheck' => '2014-10-12 09:32:46', 'urlcheckcode' => 'HTTP/1.1 302 Found', 'pauthor_id' => '01406', 'pauthor' => '!Wu, X.Z.', 'address' => 'pau', 'email' => 'pau', 'notes' => null, 'url' => '10.1246/bcsj.69.3423', 'urltype' => 'doi', 'gotpdf' => 'no', 'partial' => 'no', 'notanalyte' => '', 'citation' => ''Several factors affecting the detection sensitivity of the reaction heat-induced optical beam deflection method', Bull.

Firstly, different types of deflection detectors were compared. The experimental results showed that the bi-cell photodiode detector is most sensitive to the deflection signal. Secondly, the effect of the size of the reaction cell on the detection sensitivity was investigated. A small reaction cell gave a stable baseline and small noise in flow injection experiments, and thus gave a high detection sensitivity. Thirdly, the effects of the optical arrangements on the detection sensitivity were investigated. Focusing the probe beam close to the gold film/CCl4 interface enhanced the detection sensitivity. Also, refocusing the deflected probe beam improved the sensitivity. Under the selected experimental conditions, the detection of the neutralization reaction between HCl and NaOH at sub-nanomol level became possible. Further improvements are also discussed. 26 References', 'language' => 'English', 'updated' => '2020-12-28 11:25:15', 'sjccheck' => 'Yes', 'sjccheckdate' => '2006-07-07 02:11:38', 'hits' => '2', 'urlcheck' => '2014-10-12 09:32:46', 'urlcheckcode' => 'HTTP/1.1 302 Found', 'pauthor_id' => '01406', 'pauthor' => '!Wu, X.Z.', 'address' => 'pau', 'email' => 'pau', 'notes' => null, 'url' => '10.1246/bcsj.69.3423', 'urltype' => 'doi', 'gotpdf' => 'no', 'partial' => 'no', 'notanalyte' => '', 'citation' => ''Several factors affecting the detection sensitivity of the reaction heat-induced optical beam deflection method', Bull.

Secondly, the effect of the size of the reaction cell on the detection sensitivity was investigated. A small reaction cell gave a stable baseline and small noise in flow injection experiments, and thus gave a high detection sensitivity. Thirdly, the effects of the optical arrangements on the detection sensitivity were investigated. Focusing the probe beam close to the gold film/CCl4 interface enhanced the detection sensitivity. Also, refocusing the deflected probe beam improved the sensitivity. Under the selected experimental conditions, the detection of the neutralization reaction between HCl and NaOH at sub-nanomol level became possible. Further improvements are also discussed. 26 References', 'language' => 'English', 'updated' => '2020-12-28 11:25:15', 'sjccheck' => 'Yes', 'sjccheckdate' => '2006-07-07 02:11:38', 'hits' => '2', 'urlcheck' => '2014-10-12 09:32:46', 'urlcheckcode' => 'HTTP/1.1 302 Found', 'pauthor_id' => '01406', 'pauthor' => '!Wu, X.Z.', 'address' => 'pau', 'email' => 'pau', 'notes' => null, 'url' => '10.1246/bcsj.69.3423', 'urltype' => 'doi', 'gotpdf' => 'no', 'partial' => 'no', 'notanalyte' => '', 'citation' => ''Several factors affecting the detection sensitivity of the reaction heat-induced optical beam deflection method', Bull.

Firstly, different types of deflection detectors were compared. The experimental results showed that the bi-cell photodiode detector is most sensitive to the deflection signal. Secondly, the effect of the size of the reaction cell on the detection sensitivity was investigated. A small reaction cell gave a stable baseline and small noise in flow injection experiments, and thus gave a high detection sensitivity. Thirdly, the effects of the optical arrangements on the detection sensitivity were investigated. Focusing the probe beam close to the gold film/CCl4 interface enhanced the detection sensitivity. Also, refocusing the deflected probe beam improved the sensitivity. Under the selected experimental conditions, the detection of the neutralization reaction between HCl and NaOH at sub-nanomol level became possible. Further improvements are also discussed. 26 References', 'language' => 'English', 'updated' => '2020-12-28 11:25:15', 'sjccheck' => 'Yes', 'sjccheckdate' => '2006-07-07 02:11:38', 'hits' => '2', 'urlcheck' => '2014-10-12 09:32:46', 'urlcheckcode' => 'HTTP/1.1 302 Found', 'pauthor_id' => '01406', 'pauthor' => '!Wu, X.Z.', 'address' => 'pau', 'email' => 'pau', 'notes' => null, 'url' => '10.1246/bcsj.69.3423', 'urltype' => 'doi', 'gotpdf' => 'no', 'partial' => 'no', 'notanalyte' => '', 'citation' => ''Several factors affecting the detection sensitivity of the reaction heat-induced optical beam deflection method', Bull.

Sodium phosphate buffer (0.01M) of pH 7.4 was pumped through the cell at 1.6 ml/min and H2O2 solution was introduced using a 40 µL injector. The heat of the decomposition reaction catalyzed by the enzyme induced a deflection in the probe beam which was measured by a knife-edge and a photodiode detection system. The immobilization of catalase by crosslinking with BSA was optimized to obtain a maximum deflection signal.

Sodium phosphate buffer (0.01M) of pH 7.4 was pumped through the cell at 1.6 ml/min and H2O2 solution was introduced using a 40 µL injector. The heat of the decomposition reaction catalyzed by the enzyme induced a deflection in the probe beam which was measured by a knife-edge and a photodiode detection system. The immobilization of catalase by crosslinking with BSA was optimized to obtain a maximum deflection signal.
