Go Direct® Mini GC™

DescriptionDescriptionSpecificationExperimentsRequirementsWhat's IncludedAccessoriesDescriptionTeach students chromatography with an affordable, portable gas chromatograph that uses a unique carbon-nanotube chemiresistance detector to measure both polar and nonpolar compounds. With the easy-to-use Go Direct Mini GC, free experiments from the included e-book, and the free Vernier Instrumental Analysis™ app, students can separate, analyse, and identify substances contained in a volatile liquid or gaseous sample.Go Direct Mini GC can connect via Bluetooth® wireless technology or wired via USB to your device, providing an opportunity for you to choose the solution best for your laboratory.Developed with Seacoast Science, Go Direct Mini GC uses an efficient, software-controlled internal pump system. This design allows the Go Direct Mini GC to use room air as the carrier gas, so there is no need to purchase an external carrier gas tank or maintain a gas filtration system.Easily incorporate gas chromatography into your curriculum using our e-book Chromatography Experiments with the Go Direct Mini GC™ available for free with your purchase.You can also use this gas chromatograph to identify unknown compounds, monitor chemical reactions, and measure products from a distillation.Compound TypeTypical CompoundsRange of Acceptable Boiling PointsAlcoholsC1 - C650 - 175°CAldehydesC1 - C850 - 175°CAmidesC3 - C4150 - 250°CCarboxylic AcidsC1 - C4100 - 150°CEstersC2 - C1030 - 200°CEthersC2 - C830 - 110°CHeterocyclesC5 - C8100 - 150°CHalogenated hydrocarbonsC1 - C830 - 120°CKetonesC3 - C850 - 175°CNitrilesC2 - C550 - 120°CNitroalkane/aromaticC1 - C6100 - 210°CPhosphonatesC3 - C9180 - 210°CSulfidesC4 - C890 - 150°CAlkanes / Alkenes / AlkynesC4 - C1230 – 220°CAromaticsC6 - C1180 – 220°C This has replaced the Mini Gas Chromatograph Plus VR113720.SpecificationSpecificationValueColumnRestek MXT-502.2 Column – Siltek-treated stainless steel with proprietary diphenyl/dimethyl polysiloxane phaseColumn operating temperature30°C to 160°C with a maximum heating ramp of 10°C/minDetectorThe unique Seacoast Science carbon-nanotube chemiresistance detector is compatible with air as the carrier gas and provides sensitivity to polar and nonpolar compounds.Dimensions and weight108 mm height, 191 mm length, 133 mm width; 1.3 kgPower requirements24 VDC, 2.5 A from an external power supplyUtilityExternal power supply rated for 100–240 VAC, 1.5 A 50–60 HzCarrier gasAmbient airEnvironmental conditionsTemperature: 5°C to 40°C Humidity: 95% or less, (non-condensing environment)Liquid injection volume0.01 to 0.6 µLOperating pressure (above ambient pressure)1 to 21 kPa ExperimentsEasily incorporate gas chromatography into your curriculum using our e-book Chromatography Experiments with the Go Direct Mini GC™ available for free with your purchase.Essential instructor information and word-processing files of student instructions for each of the following experiments will be provided upon purchase.
