English to Indonesian: DETERMINATION OF REDUCING SUGARS, TOTAL REDUCING SUGARS, SUCROSE AND STARCH General field: Science Detailed field: Chemistry; Chem Sci/Eng
Source text - English Lane and Eynon method is based on the principle of reduction of Fehling’s solution by reducing sugars. Fehling’s solution is a mixture of copper sulphate and alkaline Rochelle salt (sodium potassium tartarate). Rochelle salt complexes with the cupric hydroxide formed in alkaline solution and prevent it from precipitation. Reducing sugars reduces the complexed cupric hydroxide to red, insoluble cuprous oxide. An oxidation-reduction indicator, usually methylene blue, detects the end point of the reaction. The first step in the estimation of reducing sugars by Lane and Eynon method is the determination of Factor for Fehling’s solution. Fehling factor is the quantity of invert sugar in grams required to completely reduce the Fehling’s solution (usually 5 mL each of Fehling’s A and B solutions). Total sugars include reducing sugars and non-reducing di - and oligosaccharides like sucrose, which on mild acid hydrolysis are converted into reducing sugars. Starch is hydrolysed by strong acids into glucose.
Translation - Indonesian Metode Lane dan Eynon didasarkan pada prinsip reduksi larutan Fehling dengan gula pereduksi. Larutan Fehling adalah campuran tembaga sulfat dan garam alkalin Rochelle (Natrium Kalium Tartarat). Kompleks garam Rochelle dengan tembaga hidroksida terbentuk dalam larutan alkali dan mencegahnya dari pengendapan. Gula pereduksi, mereduksi kompleks tembaga (II) hidroksida menjadi berwarna merah, yaitu tembaga (II) oksida yang tidak larut. Indikator oksidasi-reduksi, biasanya metilena biru untuk mendeteksi titik akhir reaksi. Langkah pertama dalam estimasi gula pereduksi dengan metode Lane dan Eynon adalah penentuan faktor untuk larutan Fehling. Faktor Fehling adalah kuantitas gula invert (gula sesudah hidrolisis) dalam gram yang dibutuhkan untuk mereduksi larutan Fehling secara sempurna (biasanya 5 mL masing-masing larutan Fehling A dan B). Jumlah gula termasuk gula pereduksi dan non-pereduksi, disakarida dan oligosakarida seperti sukrosa, yang pada hidrolisis asam ringan diubah menjadi gula pereduksi. Pati dihidrolisis oleh asam kuat menjadi glukosa.
English to Indonesian: ICP-OES equipment General field: Science Detailed field: Chemistry; Chem Sci/Eng
Source text - English ICP-OES (Inductively coupled plasma - optical emission spectrometry) is a technique in which the composition of elements in (mostly water-dissolved) samples can be determined using plasma and a spectrometer. The technique has been commercially available since 1974 and thanks to its reliability, multi-element options and high throughput, it has become a widely applied in both routine research as in more specific analysis purposes.
Translation - Indonesian ICP-OES (Plasma Gandeng Induktif - Spektrometri Emisi Optik) adalah suatu teknik dimana komposisi unsur-unsur (kebanyakan larut air) di dalam sampel dapat ditentukan dengan menggunakan plasma dan spektrometer. Teknik ini telah tersedia secara komersil sejak tahun 1974 dan berkat keandalannya dalam pilihan multi unsur dan kinerja yang tinggi, teknik ini telah diterapkan secara luas baik dalam penelitian rutin maupun dalam tujuan analisis yang lebih spesifik.

Bio
Hello, world!
My name is Ratih Dewi from Indonesia.
My professional background is in chemistry, analytical chemistry, also food science and technology.
I like to read, study and translate many international journals and official methods of analysis, such as Official Methods of Analysis (AOAC), American Oil Chemists' Society (AOCS), APHA, ASTM, British Pharmacopeia (BP), European Pharmacopeia (EP), European Union Reference Laboratory (EURL), Farmakope Indonesia, IEC International method, ISO, BS EN, U.S. Food and Drug Administration, USP & NF, etc.
I have a particular interest in studying international journals, and a flair for translating them from English to Indonesia and vice versa.
I have a lot of translation experience in the analytical chemistry fields, and I have translated, edited, and made many work instructions, flow charts, Standard Operational Procedure (SOP), and other documents hierarchy according to ISO 17025 and ISO 9001.
Please feel free to contact me if you need any further information. Thank you.
