GC2060 type large-screen LCD Chinese precision, special gas chromatograph air total non-methane hydrocarbons and hydrocarbon detection methods Roundup: usually refers to all volatile hydrocarbons except methane (mainly the C2 ~ C8), Also known as non-methane hydrocarbons. NMHC atmosphere above a certain concentration, harmful to human health, but also can produce chemical fumes, causing harm to the environment and humans. Concentration of standard factory sector "Air Pollutant Emission Standards" (GB16927-1996) of non-methane hydrocarbons for 5mg / m3. Detection methods for monitoring ambient air and industrial emissions of NMHC There are many ways, but most countries] adopted gas chromatography. As a direct measurement instrument used NMHC expensive, so we use two columns hydrochlorothiazide flame ionization detector gas chromatography measured total hydrocarbons and methane content respectively, the difference between the content of NMHC. Under the specified conditions the measured total amount of NMHC is in addition to methane hydrocarbons in gas chromatography with flame ionization detector significant response in the carbon count. Gas chromatographic analysis of the total system hydrocarbon / NMHC / specialization GC system, mainly based on: HJ604-2011 "total hydrocarbons in ambient air by gas chromatography", HJ / T38-1999 "national pollution discharge methane Africa total hydrocarbons by gas chromatography "and other standards, the use of hydrochlorothiazide flame detector / dual fixed volume injection valve injector design; only one injection simultaneous analysis of total hydrocarbons and total non-methane hydrocarbons, the minimum detectable concentration 0.05 mg / m3. Instrument features: ◆ dihydrotestosterone double flame tube fixed volume injection valve injector designed two special columns - can complete the total hydrocarbon / NMHC on a machine to meet HJ604-2011, HJ / T38- 1999, request; ◆ once injection is complete determination of the total hydrocarbon gas sample, methane and non-methane hydrocarbon content - there is no change in the test conditions and quantitative difficult problem; test improved 4-5 times faster than the standard method of speed of analysis; ◆ dual fixed volume injection valve injection analysis of total non-methane hydrocarbons, easy operation, good repeatability, high accuracy and high efficiency - avoid repeated injections to control human error; (make experiments operator liberation from tedious operation out of trouble, provide efficiency, while ensuring good data repeatability and accuracy) ◆ dedicated chromatography workstation, without manual calculations (including oxygen and methane peak peak deduction deductions), according to the corresponding standards, step in place to complete all of the data conversion calculations and direct outcome; instrument configuration: Gas chromatograph GC-2060 hosts a single injection of a double air route FID analyzer detects injection analysis system dedicated two columns two 100ml glass a standard gas syringe (with pressure reducer) bottles of computers, printers and a host Introduction: GC-2060 gas chromatograph is Beijing Hong Yuan Science and Technology Co., Ltd. recently launched a whole new computer-controlled multi-purpose gas chromatograph. Instruments fully absorb foreign advanced technology similar products, extensive use of SMD components, so that GC-2060's with unprecedented accuracy, efficiency and reliability; and a more simple and reasonable in structure; humane Chinese menu fast function keyboard, exquisite designs, let workers use chromatographic analysis more confident. GC-2060 gas chromatograph analysis is widely used in various areas of petrochemicals, fine chemicals, bio-medicine, environmental protection, food hygiene, high-purity gas, electricity, brewing, research and education. Main features ※ Large-screen LCD display in Chinese. Easy to learn. ※ self-diagnosis, over-temperature shutdown protection, file storage, recall, fifth-order temperature-programmed functions, with single-column automatic compensation function; can guarantee the stability of temperature programmed baseline analysis. ※ instrument with dual packed column inlet capillary column three, three independent gas path. ※ with six independent temperature control area, after intelligent door systems, cooling is very fast; each gasification chamber, detector and amplifier are modular in design, installation and replacement is very convenient. ※ complete with a separate analysis of the capillary system, independent of the capillary split injector (including membrane cleaning, and makeup shunt regulator). Optional capillary split / splitless injector. ※ instrument equipped with a flame ionization detector, thermal conductivity detector, a flame photometric detector, electron capture detector, NPD five kinds of detectors, three detectors can be installed, the user can analyze the requirements according to their own matching , also increase the six-way injection valve, the reformer apparatus and the like; and to achieve a detector in series and in parallel. ※ The main technical indicators Temperature indicators Temperature Zone: Box column, injector, detector ※ Temperature range: the temperature 5 ℃ ~ 450 ℃ (increment 1 ℃) ※ Temperature accuracy: better than ± 0.1 ℃ ※ temperature program: Eight-order rate of 0.1 ℃ ~ 40 ℃ / min (increments of 0.1 ℃) GC-2060 Series gas chromatograph each detector main technical indicators index detector sensitivity drift (30min) linear flame FID Mt <5 × 10- 11g / s (n-hexadecane) <2.5 × 10-14A> 106 thermal conductivity TCD S> 3000mv.ml/mg (n-hexadecane) <0.05mv> 104 electron capture ECD M1 <1 × 10-13g / ml (r-666) <0.05mv> 104 N and P NPD N: M1 <5 × 10-12g / s (azobenzene) P: M1 <2 × 10-12g / s (malathion) <1 × 10-12A> 104 FPD FPD M1 <5 × 10-11g / s (thiophene in S) M1 <3 × 10-11g / s (methyl parathion in P) <1 × 10-13A> 102 > 103
